Perovskite solar cells (PSCs) have been widely studied due to high light-absorption coefficient, the modulation of Fermi energy level of the overall perovskite was abstracted to a change in the perovskite doping strategy, and the photovoltaic (PV) performance of PSCs under different doping conditions of perovskite was systematically
Their inimitable features such as strong absorption ability, direct photogeneration of free carriers, long carrier diffusion lengths, ease of fabrication, and low production cost triggered the development of perovskite solar cells (PSCs) at an incredible rate, which soon reached power conversion efficiencies up to the commercialized level.

Inorganic perovskite nanocrystals and perovskite nanocrystals with doping characteristics are not only used in PSCs but also widely used in traditional silicon-based solar cells. The limitation of PCE for silicon-based solar cells can be attributed to the low spectral response at ultraviolet and blue wavelengths (300–450 nm).
