Research topics from publications: All-inorganic lead halide perovskites: a promising choice for photovoltaics and detectors; Developing Seedless Growth of ZnO Micro/Nanowire Arrays towards ZnO/FeS2/CuI P-I-N Photodiode Application. Representative work: By engineering the composition, size and surface, all-inorganic perovskites with outstanding performance and stability have been achieved for photovoltaic and detector applications A seedless hydrothermal method is developed to grow high density and vertically aligned ZnO micro/nanowire arrays with low defect density on metal films under the saturated nutrition solution. In particular, the mechanism of seedless method is discussed here. A buffer layer can be confirmed by transmission electron microscopy (TEM), which may release the elastic strain between ZnO and substrate to achieve this highly mismatched heteroepitaxial structures. Based on ZnO micro/nanowire arrays with excellent wettability surface, we prepared ZnO-FeS2-CuI p-i-n photodiode by all-solution processed method with the high rectifying ratio of 197 at ± 1 V. Under AM 1.5 condition, the Jsc of 0.5 mA/cm(2
