FILM FOR BACK-SURFACE PROTECTIVE SHEET OF SOLAR CELL MODULE, SOLAR CELL MODULE USING IT

摘要

PROBLEM TO BE SOLVED: To protect a solar cell while maintaining stability in long term use by preventing a plastic film on the outdoor exposed surface from yellowing under impact of sunlight while improving the partial discharge voltage of the solar cell.

SOLUTION: A film for the back-surface protective sheet of a solar cell module has: B layer consisting of a plastic film having hydrolysis resistance; and A layer adjacent to the B layer and having a 1×107-1×1012surface resistance and a 5% or less mean transmittance for the wavelength of 350-360 nm.
