Back surface protection sheet for solar cell module, solar cell module, and method for producing back surface protection sheet for solar cell module

摘要

Provided are a back protective sheet for a solar cell module, a solar cell module, and a method for manufacturing a back protective sheet for a solar cell module that can suppress performance deterioration due to the PID phenomenon. The 10-point average roughness Rz specified by JIS B0601-1994 is 5 to 100 μm, and the ratio between the 10-point average roughness Rz and the average interval S of local peaks specified by JIS B0601-1994 (Rz / S) A vinylidene fluoride resin film having a thickness of 1 to 10 is disposed in the outermost layer to form a back surface protective sheet for a solar cell module. And a solar cell module is comprised using this back surface protection sheet for solar cell modules.
