Abstract

Disclosed herein is a backsheet for a photovoltaic module. The backsheet includes a dielectric layer, an adhesive layer disposed on the dielectric layer, a barrier layer disposed on the adhesive layer and bonded to the dielectric layer via the adhesive layer, and a weather resistant layer directly disposed on and bonded to the barrier layer by a powder coating method.

Description

technical field [0001] The invention relates to a photovoltaic module (Photovoltaic Module) backboard and a preparation method thereof. Background technique [0002] A photovoltaic module is a component that converts light energy into electricity. Photovoltaic modules are usually prepared by lamination, and their main structure includes at least one solar cell string and a sealing system. The solar cell string is composed of a plurality of solar cells, wherein the solar cells are sealed in a transparent front sheet and a rear protection sheet (also known as a back sheet), and a polymer material is used to bond the transparent front sheet and the back sheet. The sealing system is mainly to protect the photovoltaic module and prolong its service life. In order to reduce the cost of photovoltaic modules, the research on the backplane is also the most interesting part of the industry. Among them, the main functions of the backsheet include water vapor / humidity barrier, UV res...
