Abstract: 
This work demonstrates the fabrication of a high-efficiency, hole-conductor-free, solid-state perovskite solar cell with TiO₂-nanorod arrays (NRAs) as photoanodes and commercial carbon ink as counter-electrodes. TiO₂-NRA films of various thicknesses were deposited on FTO electrodes through hydrothermal method for different reaction durations. The effect of the thickness of TiO₂-NRA films on device performance was investigated in detail. The TiO₂ NRAs/CH₃NH₃PbI₃/C devices based on 688 nm-thick TiO₂-NRA films exhibited the optimal performance and power conversion efficiency (PCE) of as high as 8.56%. This value is comparable with the PCE of the recently reported TiO₂ NRA/Perovskite/HTM/Au solar cell.
