Solar cells prepared using organic-inorganic hybrid perovskite materials exhibit advantages of high conversion efficiency and low-cost, which show extremely rapid development and attracted considerable attention in recent years. The device performance is highly dependent on the morphology of the perovskite film. In this paper, on the basis of reviewing the recent progress on the perovskite solar cells, main methods for fabricating the perovskite absorption layer are summarized, and then focus on the research progress of one-step solution method, two-step sequence deposition method, vapor deposition and electrode deposition method. Finally, we would like to give a perspective view on the efficient and stability and address the concerns about perovskite solar cells.
