摘要：

A low-cost Si nanowire array/perovskite hybrid solar cell is proposed and simulated. The solar cell consists of a Si p-i-n nanowire array filled with CH3NH3PbI3, in which both the nanowires and perovskite absorb the incident light while the nanowires act as the channels for transporting photo-generated electrons and holes. The hybrid structure has a high absorption efficiency in a broad wavelength range of 300 similar to 800 nm. A large short-circuit current density of 28.8 mA/cm(2) and remarkable conversion efficiency of 13.3% are obtained at a thin absorber thickness of 1.6 mu m, which are comparable to the best results of III-V nanowire solar cells.
