Organohalide lead perovskite solar cell is highly efficient and low cost in the fabrication process. It has attracted much attention and been widely investigated all around the world. This review looks back into the history of the organohalide lead perovskite solar cells (PSCs) and gives a brief introduction of the research progress of the PSCs. It emphatically points out the relationship between the components of the perovskite ( A cation,B cation and X anion ) and its photoelectrical properties. We classify the PSCs into three types, namely sensitized PSCs, meso-superstructure PSCs and planar heterojunction PSCs. What's more, we point out the issues concerned the developments of PSCs. The future directions are also indicated. Finally, as a high-efficiency new comer to the solar cell family, the potential benefits on the human society are expected.
