| Popis: | Thin films of antimony sulfide-selenide solid solutions (Sb2Sx Se3–x) were prepared by chemical bath deposition and thermal evaporation to constitute solar cells of a transparent conductive oxide (FTO)/CdS/Sb2Sx Se3–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 Sb2S1.5Se1.5 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/cm2under AM 1.5G (1000 W/m2) solar radiation. For all-chemically deposited solar cells of Sb2S1.1Se1.9 absorber, these values are: 2.7%, 0.44 V, and 15.8 mA/cm2, and for Sb2S0.8Se2.2, they are: 2.5%, 0.38 V and 18 mA/cm2.
