BACK SHEET FOR SOLAR CELL MODULE AND SOLAR CELL MODULE Russian patent published in 2013 - IPC H01L31/42 H01L31/18 

FIELD: physics.

SUBSTANCE: back sheet for a solar cell module has a substrate sheet and a cured layer of a coating film made of coating material, formed on one side or each side of the substrate sheet, wherein said coating material contains a fluoropolymer (A), having repeating units based on fluoro-olefin (a), repeating units based on a monomer (b) which contains a cross-linking group, and repeating units based on a monomer (c) which contains alkyl groups, where the C_2-20 linear or branched alkyl group does not have a quaternary carbon atom, and unsaturated polymerisable groups are bonded to each other through an ether bond or an ester bond. Also disclosed is a solar cell module using said back sheet and versions of a method of making the back sheet for the solar cell module.

EFFECT: making a cured flexible layer with good adhesion by eliminating fissuring, break-up, thickening and delamination.
