Abstract
- Antimony selenide (Sb<subscript>2</subscript>Se<subscript>3</subscript>) is an emerging photovoltaic material. We demonstrate that PbI<subscript>2</subscript> is an effective p-type dopant for Sb<subscript>2</subscript>Se<subscript>3</subscript>. The Sb<subscript>2</subscript>Se<subscript>3</subscript> film was doped by PbI<subscript>2</subscript> by thermal diffusion. Both the hole concentration and conductivity are dramatically increased by doping. We fabricated the Sb<subscript>2</subscript>Se<subscript>3</subscript> solar cell using C<subscript>60</subscript> as an electron transport layer by vacuum thermal evaporation. By PbI<subscript>2</subscript> doping, the open-circuit voltage (V<subscript>oc</subscript>) is increased from 0.32 to 0.38 V, and the power conversion efficiency is improved from 2.87% to 4.43%. This work provides an effective p-type dopant for Sb<subscript>2</subscript>Se<subscript>3</subscript>. [ABSTRACT FROM AUTHOR]
