A compact hole blocking layer is necessary for high efficient perovskite solar cell, which was usually fabricated by spin coating or spray pyrolysis with the followed annealing process, or vacuum deposition. Here, we deposited TiO2 compact layers by an in-situ room-temperature solvent method, which were applied as an effective hole blocking layer for hole-conductor-free perovskite solar cells with carbon electrodes. The thickness of the TiO2 compact layer can be easily regulated by the depositing time. By optimizing the TiO2 depositing time, the power conversion efficiency of hole-conductor-free perovskite solar cells was up to 10.66%.

The hole blocking layer plays an important role in suppressing recombination of holes and electrons between the perovskite layer and fluorine-doped tin oxide (FTO). Morphological defects, such as cracks, at the compact TiO2 hole blocking layer due to rough FTO surface seriously affect performance of perovskite solar cells (PSCs). Herein, we employ a simple spin-coating SnO2 thin film solution to cover cracks of TiO2 hole blocking layer for PSCs. The experiment results indicate that the TiO2/SnO2 complementary composite hole blocking layer could eliminate the serious electrical current leakage existing inside the device, extremely reducing interface defects and hysteresis. Furthermore, a high efficiency of 13.52% was achieved for the device, which is the highest efficiency ever recorded in PSCs with spongy carbon film deposited on a separated FTO-substrate as composite counter electrode under one sun illumination.
