PROTECTIVE SHEET FOR SOLAR CELL AND PRODUCTION METHOD THEREFOR, BACKSHEET MEMBER FOR SOLAR CELL, BACKSHEET FOR SOLAR CELL AND SOLAR CELL MODULE

摘要

PROBLEM TO BE SOLVED: To provide a protective sheet for solar cell exhibiting excellent adhesion to a sealing material and ensuring adhesion to a sealing material even after aging under heat and humidity environment, and to provide a production method of a protective sheet for solar cell having enhanced cleanability capable of producing a protective sheet for solar cell stably over a long period of time.SOLUTION: The protective sheet for solar cell has a base film, and an olefin based polymer layer arranged at least on one side of the base film and containing at least one kind of olefin based binder. The olefin based polymer layer contains 8 mass% or less of ether based polyurethane resin for the olefin based binder.
