文摘

Thin films of antimony sulfide-selenide solid solutions (Sb<sub>2sub>S<sub>xsub> Se<sub>3&ndash;xsub>) were prepared by chemical bath deposition and thermal evaporation to constitute solar cells of a transparent conductive oxide (FTO)/CdS/Sb<sub>2sub>S<sub>xsub> Se<sub>3&ndash;xsub>/C&ndash;Ag. The cell parameters vary depending on the sulfide-selenide composition in the films. The best solar cell efficiency of 3.6% was obtained with a solid solution Sb<sub>2sub>S<sub>1.5sub>Se<sub>1.5sub> prepared by thermal evaporation of the precipitate for which the open circuit voltage is 0.52 V and short circuit current density, 15.7 mA/cm<sup>2sup>under AM 1.5G (1000 W/m<sup>2sup>) solar radiation. For all-chemically deposited solar cells of Sb<sub>2sub>S<sub>1.1sub>Se<sub>1.9sub> absorber, these values are: 2.7%, 0.44 V, and 15.8 mA/cm<sup>2sup>, and for Sb<sub>2sub>S<sub>0.8sub>Se<sub>2.2sub>, they are: 2.5%, 0.38 V and 18 mA/cm<sup>2sup>.
