Abstract: Using perovskite materials as light absorbers of solar cells is a widely concerned new type of solar cells，the power conversion efficiency of perovskite solar cells rapidly increased from 3. 8% to 19. 3% during the year from 2009 to 2014. This paper reviews the optical properties，the preparation methods and the current research progress of perovskite materials，analyzes the research trends and the problems to be solved，and prospects the future development of the perovskite solar cells.

Key words: perovskite solar energy cells, preparation methods, solution process method, vapor deposition method
