Title:
FRONT SHEET FOR SOLAR CELL, METHOD FOR PRODUCING SAME, AND SOLAR CELL MODULE
Document Type and Number:
WIPO Patent Application WO/2018/180260
Kind Code:
A1
Abstract:
Provided is a front sheet for a solar cell which has, on a substrate, a polymer layer which contains a binder polymer and a polymer having an ultraviolet radiation-absorbing structure. In the polymer layer, the total content of monomer units derived from an olefin compound and constituent units containing a urethane bond is 50 mass% or more. With regard to the polymer layer, the total content of an ultraviolet radiation-absorbing compound and monomer units including the ultraviolet radiation-absorbing structure is 0.5-25 g/m2. The thickness of the polymer layer is 2.0-50 μm. The content of monomer units derived from a (meth)acrylic compound in the polymer layer is at least 1 mass% and less than 50 mass%. Also provided is a method for producing the front sheet for a solar cell, and a solar cell module provided with the front sheet for a solar cell.
