Carrier Diffusion in Organic-inorganic Perovskites

Hybrid organic -inorganic halide perovskites have obtained world-wide attention due to their high performance for photovoltaic and optoelectronic applications. The excellent performance of perovskite devices is determined by their outstanding photoelectric properties. However, the basic understanding of carrier transport characteristics is still limited. Here, the fundamental carrier dynamics is deeply investigated, including determining in-plane carrier diffusion in two-dimensional perovskite nanoplatelets, the details of carrier diffusion in gradient bandgap perovskites and the on-chip application of such perovskites. This research is useful for the development and optimization of perovskites and their devices.
