New-structured solar cells based on organic-inorganic perovskite materials

The solar cell based on organic-inorganic perovskite materials is a new type of solar cells, which attracts extensive attention worldwide. The perovskite solar cells are classfied into four categories according to structural difference,and their research status and latest developments are reviewed. Then the structures and performances of each type of perovskite solar cells are introduced, while the advantages and disadvantages of each type of perovskite solar cells are summarized. Finally, the future development trends of the perovskite solar cells are presented.
