Method for etching transparent thin-film solar cell component

Abstract

The invention discloses a method for etching a transparent thin-film solar cell component. The method comprises the following steps: printing oil paint of anti-etching solution in a region, which needs to be protected, of a thin-film solar cell component arranged under a screen; drying and curing the oil paint; coating etching solution on the thin-film solar cell component; and removing the oil paint. The method can realize accurately positioning the transparent region, is convenient for multiple selections of transparent patterns, contributes to realization of transparent function on the large-scale transparent thin-film solar cell component, and improves the problem that the transparent thin-film solar cell component is easily shorted.

Description

technical field [0001] The invention relates to the field of photovoltaics, in particular to an etching method for a thin-film solar cell module. Background technique [0002] In recent years, in order to develop alternative energy sources, great breakthroughs have been made in thin-film solar cell technology. Due to the beautiful appearance of thin-film batteries, combining thin-film batteries with buildings to form photovoltaic building integration has more and more extensive application prospects. When thin-film cells are used as building curtain walls, while the output performance of thin-film solar cells is emphasized, more and more attention is paid to the light transmittance of thin-film solar cells. At present, thin-film solar cell modules mostly use chemical etching and laser etching to realize the light-transmitting function. The chemical etching method in the prior art uses tape as a mask, that is, after the deposition of the amorphous silicon film, tape is atta...
