Title:
PHOTOVOLTAIC MODULE BACK SHEET AND PHOTOVOLTAIC MODULE HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2022/068017
Kind Code:
A1
Abstract:
The present invention provides a photovoltaic module back sheet and a photovoltaic module having same. The photovoltaic module back sheet comprises an insulating layer, a reflecting layer, a first decorative layer and a first transparent protective layer which are stacked in sequence, and matrix resin forming the reflecting layer and the first decorative layer is fluorine-containing resin. The matrix resin forming the reflecting layer is the same as the matrix resin forming the first decorative layer, so that the compatibility between the reflecting layer and the first decorative layer can be greatly improved, and the layering risk of the photovoltaic module back sheet is reduced. The fluorine-containing resin has good weather resistance, chemical stability, flame retardance, a low friction coefficient and the like, so that the fluorine-containing resin is selected as the matrix resin of the reflecting layer and the first decorative layer; moreover, the first transparent protective layer is arranged, so that the ultraviolet blocking rate, weather resistance, flame retardance, aesthetics and insulativity of the photovoltaic module are greatly improved. Because a pattern in the first decorative layer can fill the gap and the edge of a target photovoltaic module, the photovoltaic module back sheet has good aesthetic property.
