Abstract

The invention discloses an antimony-selenide thin-film solar battery using black phosphorene as a conducting material and a preparation method thereof. The solar battery is characterized in that the battery comprises a metal positive electrode 1, an n type heavily-doped black phosphorene film 2, an n type molybdenum disulfide 3, an intrinsic hydrogenated nano crystalline silicon film 4, a p type antimony selenide film 5, a p type heavily-doped black phosphorene substate 6, and a metal negative electrode 7. According to the invention, the solar battery has the following advantages: the molybdenum disulfide being a direct band-gap semiconductor material is used to form a buffer layer, the antimony selenide having a high absorptivity is used as absorption layer, the intrinsic hydrogenated nano crystalline silicon is used for realizing passivation of a pn junction interface, so that the defect-mode density of the interface is reduced; and because the black phosphorene is used as the conducting material, the series resistance of the battery is reduced, the light current is increased substantially, and the photoelectric conversion efficiency of the antimony-selenide thin-film solar battery is improved.

Description
