Research progress in nano-material of light-absorption layer in perovskite solar cells

From 2013，the researches on perovskite solar cell have gained breakthrough progress.Recently，perovskite solar cells have received substantial worldwide attention.Over thousand papers and patents have be published or opened both in China and abroad in recent three years.Because of the poor stability and lacking of mature related supporting materials tech- nology，the proceeding of scale-up test and industrialization has been severely hindered.The constitution，main functions， preparation methods，and application methods of light-absorption layer nano-materials in perovskite solar cell as well as re- lated patent technology progress and their shortages or corrective directions were reviewed through analyzing a large amount of new opened patents in perovskite solar cell area，which may inspire researchers getting novel ideas to develop new inorganic nano-materials to match the need of further study and industrialization of perovskite solar cells.
