Title The preparation of Perovskite solar cells and its study of stability
Abstract
The organic-inorganic perovskite solar cells have more advantages,such as high energy conversion efficiency and lower cost.In recent years,we had made many research for this kind of perovsike splar cells,under the high attention of development is very rapid.In this article,firstly we briefly introduced the research progress of the perovsike solar cells.Including the photoelectric properties of perovskite materials, preparation methods, mesoscopic perovskite, and plane heterogenerous structure of solar cells.Then, it point out some hot issues in the progress of the solar cells which we need to solve and some possible ways to further enchance the efficiency of cells. Against this research,we make some cells, and focus on the stability of perovskite solar cell, designing the related experiment,and then analyze experiment results.
