Abstract

The invention discloses a copper-indium-gallium-selenium thin-film solar cell absorption layer surface treatment device which comprises a first cleaning chamber, a first air knife drying chamber, a chemical reaction chamber, a second air knife drying chamber, a second cleaning chamber and a heatingand drying chamber which are sequentially communicated, and each chamber is internally provided witha conveying roller way for conveying a substrate; plasma water spraying equipment is arranged above the conveying roller ways in the first cleaning chamber, and rolling brush cleaning equipment is arranged between the conveying roller ways at intervals; an air knife blow-drying machine is arranged at the upper part in the second air knife drying chamber; a chemical dissolving agent is stored in the chemical reaction chamber and is used for dissolving selenide and sulfide of the solar cell absorption layer; a drying fan is arranged in the heating and drying chamber. According to the treatment device, particles and burrs on the surface of the absorption layer can be simply and conveniently treated, and the surface appearance of the absorption layer is optimized.

Description

technical field [0001] The invention relates to the technical field of thin film solar energy, in particular to a surface treatment device for the absorbing layer of a copper indium gallium selenium thin film solar cell. Background technique [0002] Photovoltaic power generation is an efficient and clean energy utilization method in today's society. As of the end of 2018, the cumulative installed capacity of photovoltaic modules in the world exceeded 510GW, of which copper indium gallium selenium thin film solar cells accounted for 2.05GW, and the compound annual growth rate in the next five years (2018-2022) will be about 16.53%. Among various solar cells that have been commercialized, copper indium gallium selenide thin film solar cells have gradually expanded their application fields due to their high theoretical efficiency, low material consumption, and low production energy consumption, especially those prepared on float glass. Thin-film batteries have the advantages ...
