Due to a suitable band gap and high optical absorption in the visible spectrum, copper bismuth sulfide (CBS) has raised concern as one of the potential photovoltaic absorber materials. In this work, CBS thin films were prepared by co-evaporating metal bismuth and CuS materials in a vacuum system and following by an annealing process. Morphologies, compositions, structures, electrical and optical properties of CBS thin films were all investigated. Finally, a completed photovoltaic device based on CdS/CBS heterojunction was fabricated and an efficiency of 1.7% was obtained in the current states. All of those analyses indicated CBS thin films a kind of suitable absorber material for the photovoltaic application. [ABSTRACT FROM AUTHOR] |
