Title:
REAR SURFACE PROTECTIVE SHEET AND SOLAR CELL MODULE USING THE SAME
Document Type and Number:
Japanese Patent JP2016072540
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rear surface protective sheet for a solar cell module having high adhesion and adhesion durability which can sufficiently contribute to enhancement in a photovoltaic power generation conversion efficiency.SOLUTION: There is provided a rear surface protective sheet for a solar cell module in which a polypropylene resin-based adhesion-reinforcing layer formed on a base material layer of the rear surface protective sheet has a multilayer structure including a core layer and a skin layer, the skin layer uses polypropylene (PP) containing an ethylene unit having a predetermined melting point range at a constant rate, a content of the polypropylene resin having a melting point of 160°C or higher in the core layer is 80% or more, and a prism structure in which a plurality of fine projections are formed so as to be adjacent to each other is formed on a surface on a light-receiving surface side of the core layer.SELECTED DRAWING: Figure 2
