Abstract

A copper indium gallium selenium solar battery device is a copper indium gallium selenium solar battery based on a polyimide film-soda glass composite substrate, is composed of glass, polyimide, a molybdenum back contact layer, a copper indium gallium selenium absorbing layer, a cadmium sulfide buffer layer, a transparence window layer high resistance intrinsic zinc oxide thin film, a transparence window layer low resistance zinc aluminium oxide thin film and an aluminum top electrode and forms a laminated structure. The production method of the copper indium gallium selenium solar battery device includes that polyimide glue is applied to the glass surface to be cured to form the polyimide film-soda glass composite substrate, all layers of thin films are prepared sequentially on the surface of the polyimide film-soda glass composite substrate, and the complete copper indium gallium selenium solar battery is separated from the soda glass substrate after the complete copper indium gallium selenium solar battery is produced to obtain the flexible copper indium gallium selenium solar battery with the polyimide film serving as the substrate. The copper indium gallium selenium solar battery device has the advantages that crystal particles of copper indium gallium selenium thin film crystals based on the polyimide film-soda glass composite substrate are large. The production method is characterized in that the flexible battery is prepared through the rigid substrate, is easy to implement and is favorable for being popularized and used in a large scale.

Description

technical field [0001] The invention relates to the technical field of thin film solar cells, in particular to a copper indium gallium selenium solar cell device based on a polyimide film-soda glass composite substrate and a preparation method thereof. Background technique [0002] Copper indium gallium selenide (CIGS) belongs to group I-III-VI quaternary compound semiconductors and has a chalcopyrite crystal structure.
