Abstract |
Lead halide perovskites APbX3 have attracted enormous interest as excellent light absorber material in photovoltaics with the power conversion efficiency exceeding 20% owing to their excellent optical and optoelectronic properties. Among the perovskite exhibit remarkable properties, thermal and air stability are critical for application.
Herein, we report a novel ultrasound-induced synthesis method that can be applicable for wide-range composition A4PbX6 perovskite, where A = CH3NH3 or Cs and X = Cl or Br, I. So called Zero-dimensional perovskite, A4PbX6 perovskite NCs are new frontier of perovskite-based materials show distinctive optical properties. Ultrasonic irradiation accelerates the dissolution of precursors in toluene, which determines the growth rate of NCs. It serves as a practical method to achieve monodisperse A4PbX6, broadening the library of metal-halide perovskite nanomaterials.
