Title:
SOLAR CELL BACK SURFACE SEALING SHEET
Document Type and Number:
WIPO Patent Application WO/2007/148754
Kind Code:
A1
Abstract:
There is provided a solar cell back surface sealing sheet which prevents a material
degradation due to hydrolysis in an actual environment in which it is used as a
solar cell module and in a high temperature and humidity acceleration test of
a solar cell module. The sheet also maintains electrical output characteristics
as a solar cell, and excels in antiweatherability. The solar cell back surface
sealing sheet has a laminated body formed by laminating at least two or more layers
of a base material with a polyurethane adhesive, wherein the polyurethane adhesive
includes an adhesive with hydrolysis resistance satisfying the following two
conditions; condition (1), wherein laminate strength after storing in a HAST
chamber, which is an acceleration test equipment by pressurized steam, for 168
hours at 105°C and 1.05 atm is at least 1N/15mm or more, and condition (2),
wherein separation between the substrates due to delamination does not occur
after storing in a HAST chamber, which is an acceleration test equipment by pressurized
steam, for 168 hours at 105°C and 1.05 atm.
