摘要：Recently, the perovskite solar cells have attracted widely attentions due to their high photoelectric conversion efficiency and simple preparing processes. Uniformity and high crystalline perovskite film was synthesized via the two-steps deposition process. In comparison with the CH3NH3PbBr3 perovskite films, the CH3NH3PbI3 perovskite film showed the better absorbance of visible light and near-infrared. The preparing process play an important role in forming high quality perovskite films. The two-steps deposition process could get the high quality CH3NH3PbI3 perovskite films. Meanwhile, scanning electron microscopy measurement indicated that the perovskite films with good compactness and no obvious grain cracks. The TiO2 was introduced to act as the electron selective layer and result in efficient electrons extraction and holes blocking. As a result, the photoelectric conversion efficiency of 13.53% was achieved with good reproducible. (C) 2017 Published by Elsevier
