The latest research progress on perovskite solar cell assembly,structure and performance and other related properties was reviewed. The device stability,material growth and toxicity,controversy on their electrical properties,working mechanism and structural optimization were summarized. Growing high quality perovskite film,understanding their basic physical and chemical properties,and clarifying the photogenerated carrier transport mechanism are all important issues. We proposed that high quality perovskite film can be obtained by optimizing growth conditions. Then their physical properties can be measured with semiconductor characterization methods.Energy band theory can be used to design and optimize the cell structure and photo-generated carriers generated,separation,collection and transport process should be explored.
