Thermal Evaporation and Characterization of Sb<sub>2</sub>Se<sub>3</sub> Thin Film for Substrate Sb<sub>2</sub>Se<sub>3</sub>/CdS Solar Cells
Abstract
Sb<sub>2</sub>Se<sub>3</sub> is a promising absorber material for photovoltaic cells because of its optimum band gap, strong optical absorption, simple phase and composition, and earth-abundant and nontoxic constituents. However, this material is rarely explored for photovoltaic application. Here we report Sb<sub>2</sub>Se<sub>3</sub> solar cells fabricated from thermal evaporation. The rationale to choose thermal evaporation for Sb<sub>2</sub>Se<sub>3</sub> film deposition was first discussed, followed by detailed characterization of Sb<sub>2</sub>Se<sub>3</sub> film deposited onto FTO with different substrate temperatures. We then studied the optical absorption, photosensitivity, and band position of Sb<sub>2</sub>Se<sub>3</sub> film, and finally a prototype photovoltaic device FTO/Sb<sub>2</sub>Se<sub>3</sub>/CdS/ZnO/ZnO:Al/Au was constructed, achieving an encouraging 2.1% solar conversion efficiency- Text
