Title:
SOLAR CELL CRACKING PREVENTION SHEET AND SOLAR CELL MODULE USING SAME
Document Type and Number:
WIPO Patent Application WO/2015/129517
Kind Code:
A1
Abstract:
Provided are: a cell cracking prevention sheet for a solar cell module, said prevention sheet being capable of preventing the cracking of a power generation element during the production, transportation, and operation of a solar cell module even in environments in which the power generation element is subjected to a large bending stress; and a solar cell module using the sheet. In order to prevent the cracking of a solar cell in a solar cell module, the cell cracking prevention sheet is configured so that a solar cell back sheet and an olefin rubber composition are formed integrally, said rubber composition being formed into a sheet integrally on the back sheet at a thickness of 300 μm or more. In the rubber composition, 10 to 30 parts by weight of an olefin resin (B) are blended into 100 parts by weight of an olefin rubber (A), and the thermally-molded rubber composition exhibits a rubber hardness (JISA) of 45 to 70 and a rubber elongation of 100-500%, inclusive.
