Photovoltaic devices are commonly employed to convert light into electricity by using the photovoltaic effect, in which absorbed light causes the excitation of an electron or other charge carrier to a higher-energy state. The separation of charge carriers of opposite types leads to a voltage that can be utilized by an external circuit. Photovoltaic devices, such as photovoltaic solar cells, can be packaged together to constitute a photovoltaic array of a larger photovoltaic system, such as a solar panel. The use of photovoltaic systems to generate electricity is an important form of renewable energy that continues to become a mainstream electricity source worldwide.
The surface area necessary to take advantage of solar energy remains an obstacle to offsetting a significant portion of non-renewable energy consumption. For this reason, low-cost, transparent, organic photovoltaic (OPV) devices that can be integrated onto window panes in homes, skyscrapers, and automobiles are desirable. For example, window glass utilized in automobiles and architecture are typically 70-80% and 40-80% transmissive, respectively, to the visible spectrum, e.g., light with wavelengths from about 450 to 650 nm. The low mechanical flexibility, high module cost and, more importantly, the band-like absorption of inorganic semiconductors limit their potential utility to transparent solar cells.
In contrast to inorganic semiconductors, the optical characteristics of organic and molecular semiconductors result in absorption spectra that are highly structured with absorption minima and maxima that are uniquely distinct from the band absorption of their inorganic counterparts. However, while a variety of organic and molecular semiconductors exist, many exhibit strong absorption in the visible spectrum and thus are not optimal for use in window glass-based photovoltaics. Despite the progress made, there is a need in the art for improved systems, methods, and device structures in the field of transparent solar technology.

Each of smart windows 102 may be self-powered using photovoltaics 108 that are integrated with the glass or visible area of the windows. For example, photovoltaics 108 may be integrated with the glass of one or both of the upper and lower panes of a vertical sliding window. Photovoltaics 108 may include organic transparent photovoltaics, luminescent solar concentrators (LSC), or other solar technologies having transparent properties. In some instances, photovoltaics 108 may include a number of visibly transparent photovoltaic devices that absorb optical energy at wavelengths outside the visible wavelength band of 450 nm to 650 nm, for example, while substantially transmitting visible light inside the visible wavelength band. In such embodiments, photovoltaics 108 may be configured to absorb ultraviolet (UV) and/or near-infrared (NIR) wavelengths in the layers and elements of the devices while visible light is transmitted therethrough.
In some embodiments, photovoltaics 108 may be considered to be visibly transparent, at least partially visibly transparent, substantially visibly transparent, and the like. In some embodiments, photovoltaics 108 may be considered to be visibly transparent when they are characterized by an average visible transmittance (AVT) of at least 30%.

For example, smart windows 102 may include various sensors 128 and window functions 122 that are powered by the solar energy harvested by photovoltaics 108. In the illustrated example, sensors 128 include a camera facing the exterior side of the window, which may be used, in some embodiments, as part of the home's security system to monitor and detect movement occurring on the exterior of the home. Further in the illustrated example, window functions 122 include electric blinds that may open (e.g., retract up and/or rotate open) or close (e.g., extend down and/or rotate close) is response to receiving a control signal to do so. Further in the illustrated example, window functions 122 may include an electric mechanism for opening or closing the window (e.g., a motorized track).

User 104 may interact with smart home system 100 and smart windows 102 in a number of ways. For example, user 104 may use an application program running on user device 120 to connect to smart home system 100 to display information about smart windows 102 and/or to transmit control data to modify an operation of smart windows 102. Alternatively or additionally, user 104 may use smart home hub 134 to interact with smart windows 102. For example, in the illustrated example, user 104 provides the audible command “Close the windows if it starts to rain”. This command may be received by a microphone installed on either user device 120 or smart home hub 134. Upon receiving this command, smart home system 100 may create a conditional mapping between data detected by sensors 128 and a window action to be performed by window functions 122 such that smart windows 102 may be caused to close in response to determining by sensors 128 that it is raining on the exterior side of smart windows 102 (e.g., using a camera, moisture sensor, etc.).
In various embodiments, components of smart home system 200 may be more or less integrated than that shown in
In some embodiments, photovoltaics 208 may generate and send electrical power to power electronics 210, which can control and regulate the manner, including the voltage and/or current, in which the electrical power is fed into power storage 212.

In some instances, power electronics 210 is able to maximize the power delivered from photovoltaics 208 to power storage 212 by matching the voltage of photovoltaics 208 to that of power storage 212.
In some embodiments, power electronics 210 conditions the variable output of photovoltaics 208 (variable voltage and current, depending on the lighting) and controls the output to a desired voltage/current acceptable for charging the batteries or powering the various sensors. This may be accomplished using an appropriate combination of buck converters, boost converters, and/or buck/boost converters, along with various active and/or passive circuit components, such as resistors, capacitors, inductors, transistors, transformers, and diodes, among other possibilities. In some instances, power electronics 210 may employ maximum power point tracking (MPPT) which may include adjusting the load to operate close to the maximum power point on the current-voltage curve of photovoltaics 208, which changes based on lighting condition. Other functions of power electronics 210 include, but are not limited to: managing battery charging/battery draw, conditioning input/output from batteries according to battery specs and safety requirements, and implementing a microcontroller integrated circuit (IC) to run algorithms, such as the MPPT.

Without limitation, sensors 228 may include an interior- and/or exterior-facing camera, an interior- and/or exterior-facing light sensor, an interior- and/or exterior-facing motion sensor, an interior and/or exterior temperature sensor, an interior and/or exterior humidity sensor, an interior and/or exterior accelerometer, an interior and/or exterior contact sensor, an interior and/or exterior audio sensor, an interior and/or exterior moisture sensor, an interior and/or exterior air quality sensor, an interior and/or exterior smoke sensor, a leak sensor for detecting argon or krypton gas leaking from within the IGU, a parts per million (PPM) gas sensor, and the like.
Each of photovoltaic windows 202 may also include one or more window functions 222, which may be devices configured to consume the electrical power generated at the smart window to perform a particular action at the window (or “window action”). Without limitation, window functions 222 may include a window opening/closing mechanism, a window locking/unlocking mechanism, electric blinds, an electrochromic device integrated with the window glass, a polymer-dispersed liquid crystals (PDLC) film, a speaker, a microphone, lighting such as LED strip or edge lighting, a transparent organic light-emitting diode (OLED) display integrated with the window glass, and the like.
As an example operation of photovoltaic window 202 utilizing window functions 222 in conjunction with sensors 228, a light sensor integrated into and powered by photovoltaic window 202 could detect that light over a brightness threshold is passing through the smart window. In order to decrease the light passing through photovoltaic window 202, which could potentially heat up the room in which photovoltaic window 202 is installed, and the home as a result in residential applications, the window shades could be lowered to reduce the light passing through the smart window system and reduce the cooling costs of the home.
Each of photovoltaic windows 202 may also include one or more power outlets 226 for transferring electrical power. For example, power outlet 226 may serve as a port for providing power (e.g., charging) to various devices from power storage 212 or power electronics 210. In some embodiments, power outlet 226 may include a USB receptacle that provides USB charging functionality to various devices. In some embodiments, power outlet 226 can be used to charge the batteries of power storage 212 by connecting an external power source to power outlet 226, thereby causing photovoltaic window 202 to receive electrical power from an external source. In one example, on cloudy days with little sunlight, an external power source (e.g., a portable charger such as a USB power bank) can be connected to power outlet 226 to charge the batteries contained in power storage 212.
In addition to power used to power local sensors 228 and other electrical loads 236, a dedicated power outlet 226 in one of many different form factors can be provided to power window functions 222 or other components installed onto photovoltaic window 202. As an example, a USB outlet can be provided that can provide power to operate window shades that are mounted on photovoltaic window 202.
Data from sensors 228 as well as photovoltaics 208, power electronics 210, and power storage 212 can be used to implement control of the various features and functions described herein. For example, such data may be provided to a central processing unit (CPU) (not shown) of photovoltaic window 202 to be processed to provide control, for example, in conjunction with wireless communication system 216, for the devices implementing the various features and functions described herein. In some embodiments, such data may be sent to smart home hub 234 and/or user device 220 (via wireless communication system 216) in a data signal 292. These devices may receive data signal 292 and may generate control signals 294 to implement the various features and functions described herein.
The above-referenced data that may be included in data signal 292 may include data captured by sensors 228, which may be referred to as “sensor data”, as well as data provided by photovoltaics 208, power electronics 210, and/or power storage 212, which may be referred to as “power data”, which can include data on the state of photovoltaics 208, including current levels, voltage levels, and the like. The power data can then be used to track energy output as a function of time that can be used by various system components. The power data and the sensor data may be analyzed by the onboard processor of photovoltaic window 202, by smart home hub 234, and/or by user device 220. In some instances, smart home hub 234 may receive, through data signal 292, the power data from the batteries of power storage 212 themselves. Such data may indicate a state of charge of the batteries, a charging status of the batteries, or a current output of photovoltaics 208, among other possibilities.
The data received by smart home hub 234 and/or user device 220 can be used to control one or more home functions 224, which may be devices configured to perform particular actions within the home (or “home actions”). Without limitation, home functions 224 may include room lighting, exterior lighting, home heating system, home cooling system, home appliances, door locks, audio systems, and the like. Corresponding home actions may include, for example, turning on, off, or dimming the room or exterior lighting, turning on or off the home heating or cooling system, locking or unlocking a door, turning on, off, or controlling the audio system in a more specific manner, and the like.
As an example operation of smart home system 200 utilizing home functions 224 in conjunction with sensors 228, on warm summer days, as the light intensity measured at the smart window system increases or a temperature measured at the smart window system increases (as measured by photovoltaics 208 and/or sensors 228 and communicated to smart home hub 234 via wireless communication system 216), the home cooling system could be turned on in anticipation of increased cooling demand before the temperature in the home begins to increase. Alternatively, if clouds begin to decrease the light intensity or temperature measured at the smart window system, the home cooling system can be turned off in response to this decrease in measured light intensity or temperature, providing additional inputs to the home cooling system that will enable finer control of the home cooling system and resulting reductions in energy consumption. Similar functionality can be provided in relation to a home heating system.
Embodiments of the present invention are particularly applicable to residential window applications, although commercial applications are also included within the scope of the present invention. As described herein, power that is generated by the smart window can be utilized by the smart window and by components, for example, window shades, that are mounted on or in proximity of the smart window. Thus, in addition to generating power that can be fed into the power grid and utilized to offset energy consumption in the building that includes smart home system 200, the smart window itself can utilize generated power to power features that are not available in conventional windows. The features that can be provided by embodiments of the present invention span a wide variety of functions, including electrochromic control to modify the tint state of the IGU, surveillance functions enabled by cameras, temperature control functions enabled by temperature sensors, window shade control functions enabled by light sensors, and the like. Thus, smart home systems described herein enable internet-of-things (TOT) functionality without the need to provide power to one or more of the TOT devices.
As described herein, smart window systems are provided that include a number of self-powered features, both interior and exterior, including, but not limited to camera function, motion sensor function, light sensor function, temperature sensor function, humidity sensor function, contact function, for example, intrusion detection using an accelerometer that can alert a user to people or items making contact with the smart window system, communication and indication functions, for example, LED indicators to provide information to a user on the status of various system elements, and the like. Embodiments of the present invention provide functions and features that are not found in conventional windows, because conventional windows do not include a power source that can be used to power devices providing these functions and features. As a result, embodiments of the present invention provide features and functions that can be integrated into a smart window system while also being powered by power generated by the smart window system.
In contrast with a conventional window that would require an external power source to provide these features, embodiments of the present invention, but using power generated by photovoltaics 208 disposed in the IGU, do not need any external wiring, which can result in lack of mechanical integrity, breaking of atmospheric seals, and the like if an attempt to integrate such external wiring into an IGU was attempted. The integration of a power source and sensors 228 inside the IGU enables functionality not available using conventional systems. As an example, in addition to intrusion detection, an accelerometer can be used to detect interaction between a user and the window, including the lites and the frame. Tapping on the lite in accordance with a predetermined pattern could be used to generate sensor data that sends a notification, causes a window action to be performed by a window function 222 (e.g., open a window), or causes a home action to be performed by a home function 224 (e.g., open a lock), and the like.
In the various embodiments described herein, the term “electronics package” may refer to the group of electrical components contained in the electronics package (e.g., the circuit board and components attached thereto) as well as the casing, packaging, coverings, and/or box in which the group of electrical components are contained. In some implementations, the electronics package can include a box with a cover that provide insulation and waterproofing for the electrical components. The cover may further provide access to the electrical components for maintenance and/or replacement of the electrical components.
Electronics package 440 can be implemented on a printed circuit board (PCB) that is mounted in the photovoltaic window, as described more fully in relation to
In order to provide for integration with IGU 452, the form factor of electronics package 440 may correspond to the shape of the upper portion of IGU 452, in this case, a width on the order of 10 mm and a length on the order of 50 cm. In various implementations, electronics package 440 may have a wide variety of sizes and form factors. For example, electronics package 440 (or the casing, packaging, or box in which the electronics package is contained) may have a width similar to the width of the IGU's spacer, i.e., between 0.25 to 0.5 inches. In some implementations, electronics package 440 may have a width similar to the width of the entire IGU, i.e., between 0.5 to 1.0 inches. The length of electronics package 440 may be based on the length of the IGU, which may vary from window to window (e.g., 2 feet, 3 feet, 4 feet, etc.).
In some embodiments, each of exterior sensor module 460 and interior sensor module 462 includes a connector 478 (for transferring power and data to/from other components of electronics package 440), a light 480, a camera 470, a humidity sensor 468, a temperature sensor 466, an accelerometer 464, and LEDs 482. Although exterior sensor module 460 and interior sensor module 462 share common elements in this embodiment, this is not required by the present invention and exterior sensor module 460 and interior sensor module 462 can include different elements, sensors, and the like. Accordingly, a camera may be included on the exterior sensor module, but not on the interior sensor module, whereas a temperature sensor may be included in both the exterior sensor module and the interior sensor module. In some embodiments, exterior sensor module 460 and interior sensor module 462 may be bonded to an exterior side and an interior side of the glass of IGU 452, respectively. Ribbon cables or other suitable connectors can be utilized to connect exterior sensor module 460 and interior sensor module 462 to other elements of electronics package 440.

Information panel 1017 may also include power data such as an amount of electrical power stored in the photovoltaic window, an amount of electrical power currently being generated by the photovoltaic window, and the like. Information panel 1017 may further include a video stream 1019 shown in real time as captured by an exterior-facing camera of the selected photovoltaic window.
In various embodiments, user interface screen 1011 may provide buttons and other graphical control elements through which a user may interact with the home automation system. For example, in some embodiments the app can receive user input to configure the model of the home automation system, e.g., by assigning photovoltaic windows having certain window functions to certain rooms or locations within the home, by assigning home functions to certain rooms or locations within the home, by defining window actions, home actions, or mappings between sensor data, power data, window actions, and home actions, and the like.
In some embodiments, user interface screen 1011 can provide a set of home monitoring and control features 1021. These features can be selected to modify what information is displayed on user interface screen 1011 and what interactable graphical elements may be provided. In the illustrated example, home monitoring and control features 1021 include “Window Status”, “Temperature”, “Lights”, “Perimeter Check”, “HVAC”, and “Media”. In some instances, selecting one of home monitoring and control features 1021 may cause various graphical elements to be overlaid onto the 3D floor plan of the home, as will be shown in reference to

The representation may be a graphical representation. The representation may be generated at a user device (e.g., user devices 120, 220, 1920). The representation of may generated by an application program running (or executing) on the user device.
At step 1504, a user input is received via a user interface (e.g., user interface 1929) of the user device. The user input may indicate a selection of the representation of the photovoltaic window. The user input may correspond to a user (e.g., user 104) interacting with a graphical element on the user interface and/or a display (e.g., display 1937) of the user device causing the representation of the photovoltaic window to be displayed, or causing the selection of the already-displayed representation of the photovoltaic window.
At step 1506, a control signal (e.g., control signal 294) for modifying an operation of the photovoltaic window is generated. The control signal may be generated in response to receiving the user input. The control signal may be generated at the user device.
At step 1508, the control signal is sent to a wireless communication system (e.g., wireless communication systems 216, 416, 616) of the photovoltaic window.

For example, instructions 2016 may be source code (written in a human-readable programming language such as Java, C, C++, C#, Python), object code, assembly language, machine code, microcode, executable code, and/or the like. In one example, instructions 2016 are provided to computer system 2000 in the form of source code, and a compiler is used to translate instructions 2016 from source code to machine code, which may then be read into main memory 2014 for execution by processor(s) 2004. As another example, instructions 2016 are provided to computer system 2000 in the form of an executable file with machine code that may immediately be read into main memory 2014 for execution by processor(s) 2004. In various examples, instructions 2016 may be provided to computer system 2000 in encrypted or unencrypted form, compressed or uncompressed form, as an installation package or an initialization for a broader software deployment, among other possibilities.
In one aspect of the present disclosure, a system (e.g., computer system 2000) is provided to perform methods in accordance with various embodiments of the present disclosure. For example, some embodiments may include a system comprising one or more processors (e.g., processor(s) 2004) that are communicatively coupled to a non-transitory computer-readable medium (e.g., memory device(s) 2012 or main memory 2014). The non-transitory computer-readable medium may have instructions (e.g., instructions 2016) stored therein that, when executed by the one or more processors, cause the one or more processors to perform the methods described in the various embodiments.
In another aspect of the present disclosure, a computer-program product that includes instructions (e.g., instructions 2016) is provided to perform methods in accordance with various embodiments of the present disclosure. The computer-program product may be tangibly embodied in a non-transitory computer-readable medium (e.g., memory device(s) 2012 or main memory 2014). The instructions may be configured to cause one or more processors (e.g., processor(s) 2004) to perform the methods described in the various embodiments.
In another aspect of the present disclosure, a non-transitory computer-readable medium (e.g., memory device(s) 2012 or main memory 2014) is provided. The non-transitory computer-readable medium may have instructions (e.g., instructions 2016) stored therein that, when executed by one or more processors (e.g., processor(s) 2004), cause the one or more processors to perform the methods described in the various embodiments.
The methods, systems, and devices discussed above are examples. Various configurations may omit, substitute, or add various procedures or components as appropriate. For instance, in alternative configurations, the methods may be performed in an order different from that described, and/or various stages may be added, omitted, and/or combined. Also, features described with respect to certain configurations may be combined in various other configurations. Different aspects and elements of the configurations may be combined in a similar manner. Also, technology evolves and, thus, many of the elements are examples and do not limit the scope of the disclosure or claims.
Specific details are given in the description to provide a thorough understanding of exemplary configurations including implementations. However, configurations may be practiced without these specific details. For example, well-known circuits, processes, algorithms, structures, and techniques have been shown without unnecessary detail in order to avoid obscuring the configurations. This description provides example configurations only, and does not limit the scope, applicability, or configurations of the claims. Rather, the preceding description of the configurations will provide those skilled in the art with an enabling description for implementing described techniques. Various changes may be made in the function and arrangement of elements without departing from the spirit or scope of the disclosure.
Having described several example configurations, various modifications, alternative constructions, and equivalents may be used without departing from the spirit of the disclosure. For example, the above elements may be components of a larger system, wherein other rules may take precedence over or otherwise modify the application of the technology. Also, a number of steps may be undertaken before, during, or after the above elements are considered. Accordingly, the above description does not bind the scope of the claims.
As used herein and in the appended claims, the singular forms “a”, “an”, and “the” include plural references unless the context clearly dictates otherwise. Thus, for example, reference to “a user” includes reference to one or more of such users, and reference to “a processor” includes reference to one or more processors and equivalents thereof known to those skilled in the art, and so forth.
Also, the words “comprise,” “comprising,” “contains,” “containing,” “include,” “including,” and “includes,” when used in this specification and in the following claims, are intended to specify the presence of stated features, integers, components, or steps, but they do not preclude the presence or addition of one or more other features, integers, components, steps, acts, or groups.
It is also understood that the examples and embodiments described herein are for illustrative purposes only and that various modifications or changes in light thereof will be suggested to persons skilled in the art and are to be included within the spirit and purview of this application and scope of the appended claims.
The disclosures of the following patent applications are incorporated by reference in their entirety for all purposes: U.S. Patent Application Ser. No. 62/836,161, U.S. Patent Application Ser.
