Abstract: As the preparation technology of photovoltaic cells attracted more and more attention,the preparation materials for photovoltaic cells have become the focus and hotspot during research and development.Based on the achievements of technical research and development in the past two years,the latest organic-inorganic hybrid photovoltaic battery materials were mainly discussed,including phenylene ethylene (PPV),pyrrole and pyrrole diketone (DPP),polythiophene (PT),benzothiophene (BDT) and other organic inorganic hybrid material.The latest preparation methods and processes were studied,and compared and analyzed the conversion performance of various photovoltaic materials in which CH3NH3PbI3-CsPbI3 was much higher than that of other materials.
