▎ 摘 要
NOVELTY - A black photovoltaic backplane comprises a photovoltaic backplane substrate (1), a black coating (2) and a protective layer (3) stacked in sequence, where the thickness of the protective layer is 1-3 μm. USE - The black photovoltaic backplane is used for preparing photovoltaic cell (claimed). ADVANTAGE - The black photovoltaic backplane is not easy to change color when the photovoltaic module is used, has good color stability, has a longer functional validity period, reduces the problem of small molecule organic matter entering the film with water vapor after the double bond of the black coating breaking caused by high temperature and high humidity, and prolongs the effective period of the highly reflective black filler. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: a preparation method of the black photovoltaic backplane comprising sequentially coating the black coating and the protective layer on the surface of the photovoltaic backplane substrate to obtain the product; and a photovoltaic cell comprising the black photovoltaic backplane. DESCRIPTION OF DRAWING(S) - The drawing shows a structural schematic diagram of the black photovoltaic backplane. 1Photovoltaic backplane substrate 2Black coating 3Protective layer
