Mesoscopic perovskite solar cells have attracted much attention due to their good stability,low cost and ease of industrialization.As the active layer in the solar cell,the perovskite-sensitized porous TiO2 layer plays an important role in the performance of the devices.Three-dimensional inverse opal TiO2 was prepared using polystyrene (PS) microspheres as template,and it was applied to carbon-based mesoscopic perovskite solar cells.The effect of TiO2 inverse opal prepared with PS microspheres of different sizes on the photoelectric properties of the solar cells was investigated.The results indicated that the cell device prepared using PS microspheres with a diameter of 800nm as template had relatively high absorption in the visible light range,and the photoelectric conversion efficiency was 2.10%.
