INFLUENȚA TRATĂRII TERMICE ÎN PREZENŢA CLORURII DE CADMIU (CdCl2) ASUPRA PROPRIETĂŢILOR FIZICE ALE CELULELOR SOLARE CU HETERONCȚIUNEA pCdTe/nCdS

The article is a comprehensive study of the effect of heat treatment in presence of a cadmium chloride (CdCl2) on the physical properties of pCdTe/nCdS solar cells. Heat treatment process plays a key role in enhancing the pCdTe/nCdS hetero-structure photosensitivity, thus improving the performance of solar cells based on them. This article outlines the changes in the structural characteristics and photoelectric properties of such solar cells before and after heat treatment process. The two most popular methods of the heat treatment process based on cadmium chloride are also discussed. One may consider the CdCl2 heat treatment process as one of the very important stages of preparing CdTe/CdO/CdS solar cells, which improves the performance of these cells made in laboratories of the State University of Moldova. Keywords: Heterojunction, Solar cell, Chloride heat treatment process, Cadmium Chloride, Cadmium Telluride, Cadmium Sulfide.
