Halide Perovskite Nanocrystals and Applications to Solar Cells

Halide perovskite nanocrystals have attracted more and more attention, because of their facile synthesis and outstanding optical and electronic properties. It has been shown that the halide perovskite nanocrystals exhibit size-dependent optical and electric properties distinct from their bulk counterparts due to strong quantum confinement effects. In this chapter, the recent development of synthesis methods of halide perovskite nanocrystals is first introduced, and the photophysics of halide perovskite nanocrystals such as exciton generation and charge extraction as well as the strategy to improve the quality of halide perovskite nanocrystals are well summarized and discussed. Finally, the application of halide perovskite nanocrystals in solar cells field is deeply discussed.
