Abstract
Abstract Antimony selenide (Sb 2 Se 3 ) has a one-dimensional (1D) crystal structure comprising of covalently bonded (Sb 4 Se 6 ) n ribbons stacking together through van der Waals force. This special structure results in anisotropic optical and electrical properties. Currently, the photovoltaic device performance is dominated by the grain orientation in the Sb 2 Se 3 thin film absorbers. Effective approaches to enhance the carrier collection and overall power-conversion efficiency are urgently required. Here, we report the construction of Sb 2 Se 3 solar cells with high-quality Sb 2 Se 3 nanorod arrays absorber along the [001] direction, which is beneficial for sun-light absorption and charge carrier…
