We report on metal-organic halide perovskite CH3NH3PbI3 films converted from PbI2 precursors for planar heterojunction perovskite solar cells. PbI2 films as a precursor were deposited by hot-wall method and conventional vacuum evaporation. The conversion to perovskite phase from the PbI2 films were performed by annealing in methyl ammonium iodine (MAI) vapour at 120-150 °C. We confirmed that no residual PbI2 phase can be detected in the converted perovskite films by x-ray diffraction measurements. The surface morphology of the perovskite films was measured by AFM. Roughness Ra of the films is 17.8 nm, which is comparable value to the reported ones. Using the converted perovskite films we fabricated tentative perovskite solar cells with a device architecture of ITO/PEDOT:PSS/Perovskite/C60/Ag. The power conversion efficiencies of the fabricated solar cells from a conventional evaporation and the hot-wall method exhibited 2.22 and 2.33%, respectively.

A series of CH3NH3PbI[Formula: see text]BrxCly mixed-halide perovskite were fabricated as light harvesters for organic–inorganic planar heterojunction perovskite solar cells (PSCs). This paper aimed at investigating the morphology and structural properties of Br doped mixed-halide perovskites and the influence on the corresponding photovoltaic performances. We found that Br incorporation in an I/Cl-based structure dramatically improved the charge transport within the perovskite layer. The average efficiency of the planar device was 13.6% with a minimal standard deviation of [Formula: see text] 1.53% and best efficiency as high as 15.13% was achieved. Moreover, the device showed superior stability over 20 days with little degradation [Formula: see text]9% when stored under ambient conditions, indicating the outstanding performances of planar heterojunction solar cells based on this material. The results highlight the crucial role of the Br doping on the performance of the PSCs and pave the way for further progress on this field.
