Title:
POLYMER SHEET AND METHOD FOR PRODUCING SAME, BACK SHEET FOR SOLAR CELLS, AND SOLAR CELL MODULE
Document Type and Number:
WIPO Patent Application WO/2013/008916
Kind Code:
A1
Abstract:
A polymer sheet characterized by comprising: a polymer support; a first polymer layer which is arranged on one surface (A) of the polymer support, contains a pigment, and has a peel force against a sealing material of 5 N/cm or more; a second polymer layer which is arranged between the surface (A) of the polymer support and the first polymer layer and comprises at least one polymer selected from a polyolefin resin, an acrylic resin and a polyester resin; a third polymer layer which is arranged on a surface (B) of the polymer support which is opposed to the surface (A) and comprises a silicone polymer; and a fourth polymer layer which is arranged on the third polymer layer and comprises a fluorine-containing polymer. The polymer sheet has a fluorinated polymer layer. Therefore, the delamination between layers in a back sheet can be prevented when the back sheet is allowed to stand for a long period under humid and hot environment. Further, the delamination between the polymer sheet and a sealing material for a solar cell module can be prevented when the polymer sheet is attached onto the sealing material and the resultant product is allowed to stand for a long period under humid and hot environment.
