摘要：

Hybrid organic-inorganic solar cells with planar heterostructure based on hydrothermal-synthesized CdS nanorods (CdS NRs) array and organometal trihalide perovskite CH3NH3PbI3 have been fabricated and characterized. Thermal annealing and Ultraviolet Ozone (UV-Ozone) treatment were applied to modify the surface of the CdS NRs, in which UV-Ozone treatment was proved to be more effective in improving the morphology of perovskite layer, as well as the charge transfer between CH3NH3PbI3 and CdS NRs. Devices structured as ITO/CdS NRs array/CH3NH3PbI3/2,29,7,79-Tetrakis-(N,N-di-p-methoxyphenyl-amine)-9,99-spirobilluorene (spiro -MeOTAD)/MoO3/Ag produced short-circuit current density of 18.77 mA/cm(2), open-circuit voltage of 0.89 V, and fill factor of 49.9%, leading to a best power conversion efficiency of 836% in the case of 10 min UV-Ozone treatment.
