| Abstract | ZnS is an important II–VI compound semiconductor with a large band gap. It is used as a key material for light-emitting diodes [1], cathode-ray tubes [2], thin film electroluminescence [3], and buffer layers in photovoltaic cells [4]. Last material application is caused by a transparency of ZnS thin films to practically all wavelengths of the solar spectrum, besides it is a “Cd-free” and “low-cost” material. Chemical bath deposition (CBD) is the commonly used method for production of ZnS layers. Even though cells with the ZnO/CBD-ZnS/CIGS structure have high efficiencies (η=18,6%) [5], manufacturing companies have sought alternatives to the CBD deposition technique [4]. It occurs, because the CBD – ZnS film includes a large amount of oxygen in the form of Zn(OH)2 and ZnO [6]. It is considered that close-spaced vacuum sublimation (CSVS) method [7] may become successful alternative to CBD-method for producing of ZnS layers with enhanced characteristics and not containing oxide phases [8]. It is besides important to know as a growth condition influence on native defects and uncontrolled impurities in ZnS films. |
