In order to improve the efficiency in the preparation of organic-inorganic hybrid perovskite （e.g.CH3- NH3 Phi3 ） solar cells, solution method will mainly be used to explore its efficient on perovskite performance. Based on this, the latest progress of solution-based devices, important factors which affecting the growth of various high quality perovskite thin films and perovskite-based perovskite thin film structes in perovskite solar cells werestudied. At the same time, the cost and stability of perovskite solar cells weretaken into consideration. The solution method mainly affects the microstructre, structre of film,material composition, impurity phase, defect / doping and interfacial properties of perovskite thin films. The conditions which figuring out the problems will ultimately affect the perovskite performance.
