Preparation of CdS thin films by chemical-bath-deposition (CBD) and chlorinated-cadmium (CdCl2) heat treatment

摘要

The present invention relates to a method of manufacturing a CdS thin film, which comprises forming a CdS thin film having a large crystal size and having a large crystal size, (CdS) thin films prepared by using a CBD method and cleaning the substrate. The present invention also relates to a method of manufacturing a flat surface of a sulfur-cadmium (CdS) thin film, ) Thin film was placed in a carbon boat specially prepared with a solution of CdCl 4 or CdCl 4 and a solution of CdCl 4 or CdS 4 and was exposed to argon, (CdS) thin film with a large crystal size and high flatness and a flat surface is manufactured by heat treatment at a high temperature for 3 to 10 minutes in an open gas atmosphere to produce a high efficiency solar cell (Che7i7al-bath-deposition) method and a chloride-card Card ium (CdS) and a method for manufacturing a thin-film CdS thin film - (Cdc17) sulfide by thermal battery.
