| Abstract |
Pb-based halide perovskites AMX3, which employ methylammonium lead halide (CH3NH3PbX3, X = I, Br or Cl) in the perovskite structure, have recently attracted much interest as new light absorber material for next generation solar cells. However, for the commercial application of PSC devices, the intrinsic material instability and the toxicity due to water soluble Pb2+ have to be overcome. Herein, we investigated an antimony chalcohalide compound, SbSeI, as a potential semiconductor material for Pb-free light absorbers of solar cells. SbSeI has a wide band gap of 1.70 eV with a density of 5.80 g/cm3, and it crystallizes in the orthorhombic crystal system with a one-dimensional chain structure. In this work, we synthesized polycrystalline antimony selenoiodide (SbSeI) powder via a solid-state reaction in evacuated Pyrex tube. The product was characterized by using techniques such as powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDAX). |
