摘要

Rapid recent improvement in photovoltaic efficiency in hybrid lead halide perovskite materials has provided the impetus for understanding other, related main-group halide systems. Here, we show that the closely related but less toxic bismuth iodide BiI_3 can show promising optoelectronic properties. Layered binary BiI_3 is used here as the active layer in planar solar cell architectures (efficiency approximately 0.3%). Experimental and computational studies of absolute band positions of BiI_3 are also presented, to help in the rational design of device architectures that would allow efficient charge transfer at the interfaces.
