Abstract
The invention provides a solar cell back plate. The solar cell back plate comprises a fluorine-containing polymer paint curing coating layer, a polyurethane coating layer, an insulating substrate layer, an adhesive layer and a heat-moisture resistant layer from downside to upside, wherein the heat-moisture resistant layer is a mixture containing ethylene-vinyl acetate copolymer and polyolefin. The invention also provides a preparation method of the solar cell back plate and a solar cell component adopting the solar cell back plate. The solar cell back plate provided by the invention has excellent adhesion performance between the layers, good water steam resistant permeability before and after the heat-moisture treatment, and low cost.
