Title:
SEALING FILM FOR SOLAR CELLS, AND SOLAR CELL MODULE
Document Type and Number:
WIPO Patent Application WO/2016/194606
Kind Code:
A1
Abstract:
Provided is a sealing film for solar cells, capable of providing sufficient load carrying capacity to a solar cell module even when the sealing film is thin. In a solar cell module having an obverse-side protective member, a solar cell element, and a reverse-side protective member, this sealing film for solar cells is disposed between the obverse-side protective member and the solar cell element or between the reverse-side protective member and the solar cell element, and contains an olefin (co)polymer. When the obverse-side protective member, the solar cell element, and the reverse-side protective member are integrated by the sealing film 13A, 13B for solar cells, the sealing film for solar cells is characterized in that the thickness of the sealing film for solar cells is 0.25-0.40 mm, and, in a measurement of stress relaxation regarding the reduction of, over the course of time, stress caused when 100% strain is given to the sealing film for solar cells at a condition of 80°C, the time required for the relaxation modulus G(t) to reduce from 5 kPa to 2.5 kPa is not longer than 7.0 seconds.
