Document Type and Number:
WIPO Patent Application WO/2018/119685
Kind Code:
A1
Abstract:
A method for producing a CdTe solar cell starting with providing a semi-finished CdTe solar cell including a CdTe forming a first surface of the semi-finished CdTe solar cell (S110). A metal layer is applied on the first surface of the semi-finished CdTe solar cell (S150) and an aqueous solution comprising metal ions or metal containing ions is applied on a back surface of the semi-finished CdTe solar cell (S120) and later removed (S140). Applying and removing the aqueous solution may be performed before or after applying the metal layer. Further, the semi-finished CdTe solar cell is additionally illuminated or an external electrical power is applied to the semi-finished CdTe solar cell (S131, S132) for a first time period of the time while the aqueous solution is present on the back surface of the semi-finished CdTe solar cell or for a second time period after removing the aqueous solution and before applying the metal layer.
