Abstract

A polyimide film-soda glass composite substrate based sodium-doped copper indium gallium diselenide solar cell device is characterized in that a substrate is composed of soda glass and a polyimide film growing on the surface of the substrate, and copper indium gallium diselenide solar cells are manufactured on the surface of the composite substrate. The sodium-doped copper indium gallium diselenide solar cell device has the advantages that the polyimide film-soda glass composite substrate based copper indium gallium diselenide film is excellent in adhesion property and good in crystallization quality, crystalline grains are large, and the defects are few; after the whole copper indium gallium diselenide solar cells are manufactured, the solar cells are separated from the soda glass to form the flexible copper indium gallium diselenide solar cells using the polyimide film as the substrate, and the flexible cells are manufactured by using the rigid substrate; a manufacturing method is simple and easy to implement, and the solar cell device is suitable for large-scale popularization and application and especially has very wide application prospect in a space occasion and special occasions.

Description

technical field [0001] The invention relates to the technical field of thin-film solar cells, in particular to a sodium-doped copper indium gallium selenium solar cell device based on a polyimide film-soda glass composite substrate and its preparation. Background technique [0002] Copper indium gallium selenide (CIGS) belongs to group I-III-VI quaternary compound semiconductors and has a chalcopyrite crystal structure. Since the appearance of copper indium gallium selenide thin film solar cells in the 1970s, it has developed very rapidly and will gradually realize industrialization. This battery has the following characteristics: ①The bandgap width of CIGS can be adjusted within the range of 1.04ev-1.67ev. ②CiInGaSe is a direct bandgap semiconductor with an absorption coefficient of up to 10 for visible light 5 cm -1 . The thickness of the CIGS absorption layer only needs to be 1.5-2.5 μm, and the thickness of the whole battery is 3-4 μm. ③It has strong anti-radiation ...
