Patent Application
20110011452
The present invention relates to a concentration photovoltaic apparatus and, more particularly, to a concentration photovoltaic apparatus for ensuring firm connection of a solar cell to an external electric device and precise positioning of the solar cell on a substrate when the solar cell is soldered to the substrate.
Referring to
There is a problem with the concentration photovoltaic apparatus. The contact 521 is very close to the solar cell 6 so that the connection of the contact 521 to the related wire 71 would be affected by the solar cell 6 which gets very hot in operation. In such a case, the supply of the electricity to the external electric apparatus 7 from the concentration photovoltaic apparatus would be interrupted.
The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art.
It is an objective of the present invention to provide a concentration photovoltaic apparatus for ensuring firm connection of a solar cell to an external electric device.
It is another objective of the present invention to provide a concentration photovoltaic apparatus for ensuring precise positioning of a solar cell on a substrate when the solar cell is soldered to the substrate.
To achieve the foregoing objectives, the concentration photovoltaic apparatus includes a substrate, a bypass diode, a solar cell and an adhesion layer. The substrate includes five conduction regions. The first conduction region is separated from the second conduction region. The third conduction region is integrated with the first conduction region. The fourth conduction region includes two cutouts therein. The fourth conduction region is integrated with the second conduction region but separated from the third conduction region. The fifth conduction region is connected to the third conduction region through a connection region. The bypass diode is provided on the fourth conduction region and formed with pins connected to the fifth conduction region. The solar cell is provided on the fourth conduction region, on a side of the cutouts, and connected to the third and fifth conduction regions through wires. The adhesion layer is provided between the solar cell and the fourth conduction region.
Other objectives, advantages and features of the present invention will become apparent from the following description referring to the attached drawings.
The present invention will be described via the detailed illustration of embodiments referring to the drawings.
