Recently, some breakthroughs about the efficiency of total solid perovskite solar battery had been made constantly, due to the outstanding optical and electrical characteristics of perovskite material. The efficiency of total solid perovskite solar battery now was up to 20%, so more expectations had been laid on the industrialization prospect of perovskite solar cells industry. In paper, some optical and electrical characteristics of perovskite material are mentioned and the development course of perovskite solar cells was also reviewed. Meanwhile, the basic photoelectric conversion process of perovskite solar cells was discussed, based on the nomal structure. And all kinds of grows structure about perovskite solar cells was classified by order, what was more, no-hole transmission layer about perovskite solar cells was discussed specially, then the advantage of industry properties about no-hole transmission layer perovskite solar cells was described, such as stability, service life and cost control. In this condition, the efficiency of no-hole transmission layer perovskite solar cells made by cheap carbon electrode was about to 15%, more improve space could be expected in future.
