The subject matter herein generally relates to solar cell modules and manufacturing method of the same.
Solar cell modules are designed to absorb the sun's rays for generating electricity or heating.
Many aspects of the disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure.
The present disclosure, including the accompanying drawings, is illustrated by way of examples and not by way of limitation. Several definitions that apply throughout this disclosure will now be presented. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like.
The protecting plate 201 has an outward surface and an inward surface. The outward surface can be coated with an ultraviolet (UV)-resistant film to extend the lifetime of the protecting plate 201. The inward surface can be coated with a cross linking agent or have microstructures formed thereon to improve the adhesion between the EVA layer 2021 and the protecting plate 201. The microstructures can assist in a vacuum suction procedure.
A manufacturing method of a conventional solar cell module must include two steps, the steps of hot pressing and of adhesion. The two step method is time consuming. Moreover, deformation of a back sheet and of a supporting structure can occur due to different thermal expansion coefficients of the back sheet and of the supporting structure and adhesion between the back sheet and the supporting structure. A manufacturing method of the solar cell module 200 of the present disclosure comprises only one step of hot pressing together the protecting plate 201, the cell structure 202, and the supporting structure 203. This manufacturing method saves time and improves efficiency. Moreover, hot pressing does not cause serious deformation of the supporting structure 203 even though the thermal expansion coefficients of materials are different.
The embodiments shown and described above are only examples. Many details are often found in the art such as the other features of a solar cell module and manufacturing method of same. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, especially in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above may be modified within the scope of the claims.
