摘要
The invention relates to a method for conditioning the CdTe layer of CdTe thin-film solar cells without the use of CdCl2. Calcium tetrachlorozincate (CaZnCl4) is to be used instead of CdCl2 for activation, and the process parameters that have proven themselves over time are to be kept. The method involves the activation of the CdTe layer of semi-finished thin-film CdTe solar cells; calcium tetrachlorozincate is applied to the CdTe layer (4) and the semi-finished thin-film CdTe solar cell subsequently undergoes a heat treatment. The calcium tetrachlorozincate layer is preferably applied via methods from the prior art, for instance roller coating with an aqueous or methanolic salt solution, spraying on an aqueous or methanolic salt solution, an aerosol coating or a dipping bath.
