摘要

PROBLEM TO BE SOLVED: To provide a polymer sheet for a solar cell, to which dust is hardly attached and from which a matting agent is hardly peeled off.;SOLUTION: A polymer sheet for a solar cell contains a matting agent 14 so that at least one of a polymer layer provided on one face 11a and a polymer layer provided on the opposite face 11b satisfies the following conditions (1)-(3). 0.06≤(A/B)≤0.8 (1), 5 mg/m²≤C≤50 mg/m² (2), (where, A represents an average particle size (unit: μm) of the matting agent, B represents the sum (unit: μm) of a film thickness of a polymer layer provided closest to a polyester support sheet among the polymer layers containing the matting agent, and, when a polymer layer is provided on the surface side of the polymer sheet as compared with the polymer layer provided closest to a polyester support sheet, the total thickness of the surface side polymer layer, C represents an additive amount of the matting agent per one face. When at least one layer of the surface side polymer layer is provided, the following condition (3) is also satisfied), and 0.1≤(A/D)≤1.1(3), (where, D represents the total thickness (unit: μm) of the surface side polymer layer).;COPYRIGHT: (C)2014,JPO&INPIT
