Title:
SHEET SET FOR SOLAR CELL SEALING
Document Type and Number:
WIPO Patent Application WO/2013/128861
Kind Code:
A1
Abstract:
The present invention is a sheet set for solar cell sealing, which comprises a first sealing sheet and a second sealing sheet and is used for the purpose of sealing a solar cell element by being arranged between a light receiving surface-side protective member and a back surface-side protective member. When the first sealing sheet and the second sealing sheet are heated and pressurized at 150°C at 100 kPa for 15 minutes after being heated and depressurized at 150°C at 250 Pa for 3 minutes, the volume resistivity of the first sealing sheet is higher than the volume resistivity of the second sealing sheet, said volume resistivities being measured at 100°C at an applied voltage of 500 V in accordance with JIS K6911. The first sealing sheet is arranged between the light receiving surface-side protective member and the solar cell element. The second sealing sheet contains at least one polar group that is selected from among a carboxyl group, an ester group, a hydroxyl group, an amino group and an acetal group.
