Abstract

The invention discloses a cadmium telluride solar cell assembly with a thermal insulation layer and a preparation method of the cadmium telluride solar cell assembly. The assembly sequentially comprises cadmium telluride power generation glass, a silica gel layer and a heat preservation layer from bottom to top, the heat preservation layer comprises a plurality of heat insulation plate layers, each heat insulation plate layer is formed by horizontally splicing a plurality of heat insulation plates, heat preservation materials are arranged in the heat insulation plates, and PET / AL / PE compositefilms are arranged on the outer surfaces of the heat insulation plates. The assembly is low in heat transfer coefficient, good in heat preservation performance and high in photoelectric conversion efficiency.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a cadmium telluride solar cell component with an insulating layer and a preparation method thereof. Background technique [0002] Cadmium telluride solar cell module is a device that directly converts light energy into electrical energy by using photovoltaic technology. Among them, cadmium telluride thin-film solar cells are widely considered to be efficient and cheap with simple structure, relatively low production cost, and the fastest commercialization progress. thin film battery. Building Integrated Photovoltaies (BIPV) refers to the installation of photovoltaic modules on the surface of the building's peripheral structure to provide power, and at the same time as a functional part of the building structure, replacing some traditional building structures such as roof panels, tiles, windows, building facades, and rain Sheds, etc., can also be made into photovoltaic multif...
