From Nanostructural Evolution to Dynamic Interplay of Constituents: Perspectives for Perovskite Solar Cells

Moving away from the high‐performance achievements in organometal halide perovskite (OHP)‐based optoelectronic and photovoltaic devices, intriguing features have been reported in that photocarriers and mobile ionic species within OHPs interact with light, electric fields, or a combination of both, which induces both spatial and temporal changes of optoelectronic properties in OHPs. Since it is revealed that the transport of photocarriers and the...
