Organolead trihalide perovskite (OTP) materials are emerging as naturally abundant materials for low-cost, solution-processed and highly efficient solar cells. Here, we show that, in OTP-based photovoltaic devices with vertical and lateral cell configurations, the photocurrent direction can be switched repeatedly by applying a small electric field of <1 V μm(-1). The switchable photocurrent, ge...
Detailed atomic-level insight into the mechanism of W(CO)6 and CO selenization is essential for fabrication cheap environmentally benign transition metal chalcogenides such as MoS2 WSe2. Earlier discussions in literature have focused mainly on methanation by sulfur its derivatives but H2Se mediated at atomic level yet to be explored. First-principles calculations ReaxFF-based molecular dynamics...
The electronic structure and optical absorption spectrum of organometal halide perovskite compound CH3NH3BiI3 as a substituting candidate of well-concerned CH3NH3PbI3 not only for environmental friendly consideration are studied using the first principles calculations. It is revealed that a Bi replacement of Pb in CH3NH3PbI3 does not change seriously the band edge structure but the bandgap beco...
