Thin films of antimony sulfide‐selenide solid solutions (Sb 2 S x Se 3– x ) were prepared by chemical bath deposition and thermal evaporation to constitute solar cells of a transparent conductive oxide (FTO)/CdS/Sb 2 S x Se 3– x /C–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 2 S 1.5 Se 1.5 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 2 under AM 1.5G (1000 W/m 2 ) solar radiation. For all‐chemically deposited solar cells of Sb 2 S 1.1 Se 1.9 absorber, these values are: 2.7%, 0.44 V, and 15.8 mA/cm 2 , and for Sb 2 S 0.8 Se 2.2 , they are: 2.5%, 0.38 V and 18 mA/cm 2 .
