Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a solar battery module having a structure capable of reducing a stress difference between a part where a power generation element is laminated and a part where no power generation element is laminated.SOLUTION: Provided is a solar battery module 1 that comprises a lamination structure consisting of a front face layer L1, an encapsulation layer L2, and a back face layer L3, and in which a plurality of power generation elements 2 are arranged in the encapsulation layer L2. The solar battery module 1 is configured by a first lamination part 10 where the power generation element 2 is provided in the encapsulation layer L2, and a second lamination part 20 where no power generation element 2 is provided in the encapsulation layer L2. In the back face layer L3, a second part 5b that configures the second lamination part 20 is formed so as to be thicker than a first part 5a that configures the first lamination part 10.SELECTED DRAWING: Figure 1
【課題】発電素子が積層している部分と発電素子が積層していない部分との応力差を低減させることができる構造の太陽電池モジュールを提供する。【解決手段】表面層L1と封止層L2と背面層L3とからなる積層構造を備え、封止層L2の内部に複数の発電素子2が配列されている太陽電池モジュール1において、封止層L2内に発電素子2が設けられている第一積層部10と、封止層L2内に発電素子2が設けられていない第二積層部20とによって構成され、背面層L3は、第二積層部20を構成する第二部分5bが第一積層部10を構成する第一部分5aよりも厚く形成されている。【選択図】図1 |
