Manufacture of solar cell module

摘要

A solar cell module is manufactured by encapsulating a solar cell matrix comprising a plurality of electrically connected solar cell components between a transparent panel and a backsheet with a resin. The method involves (i) embossing opposite surfaces of a green silicone rubber sheet, (ii) arranging a transparent panel (13a), silicone rubber sheet (11), solar cell matrix (14), silicone rubber sheet (11), and backsheet (13b) to form a multilayer assembly, and (iii) heating and compressing the assembly for vacuum lamination for establishing a seal around the solar cell matrix.

1. A method for manufacturing a solar cell module by resin encapsulating a solar cell matrix comprising a plurality of electrically connected solar cell components arranged between a transparent panel and a second panel or backsheet, comprising the steps of:
(1) providing a first laminate by laminating a green silicone rubber sheet of a millable silicone rubber composition to one surface of the transparent panel, the silicone rubber sheet having a predetermined pattern of recesses and bosses on its surface, wherein the recesses are interconnected, (2) providing a second laminate by laminating a green silicone rubber sheet of a millable silicone rubber composition to one surface of the second panel or backsheet, the silicone rubber sheet having a predetermined pattern of recesses and bosses on its surface, wherein the recesses are interconnected, and (3) mating the first and second laminates together such that the patterned surfaces of the silicone rubber sheets may be opposed to each other, placing the solar cell matrix between the first and second laminates, pumping a space surrounding the laminates to vacuum, wherein air in the spaces between the solar cell matrix and the green silicone rubber sheet of the first laminate and between the solar cell matrix and the green silicone rubber sheet of the second laminate is evacuated through channels defined by the interconnected recesses of the green silicone rubber sheets of the first and second laminates upon the vacuum pumping, compressing and heating the first and second laminates in vacuum to cure the silicone rubber sheets for establishing a seal around the solar cell matrix; wherein step (1) includes embossing at least one surface of the green silicone rubber sheet of silicone rubber composition and laminating the embossed silicone rubber sheet to the surface of the transparent panel such that the embossed surface of the silicone rubber sheet may be disposed remote from the transparent panel; and wherein both surfaces of the green silicone rubber sheet are embossed to have a predetermined pattern of interconnected recesses and bosses on its surfaces, respectively, and wherein air in the spaces between the solar cell matrix and the green silicone rubber sheet of the first laminate and between the transparent panel and the green silicone rubber sheet of the first laminate is evacuated through channels defined by the interconnected recesses of the green silicone rubber sheet of the first laminate upon the vacuum pumping of step (3).
