Abstract

A new nearly cubic NH₂CH=NH₂PbI₃ (FAPbI₃) perovskite was synthesized for the mesoscopic solar cells. The measured band gap of bulk FAPbI₃ is 1.43 eV and it is therefore potentially superior than the CH₃NH₃PbI₃ (MAPbI₃) as the light harvester. A homogeneous FAPbI₃ perovskite layer was deposited on the TiO₂ surface by utilizing the in situ dipping technology. As a result, a high efficiency of 7.5% was achieved using P3HT as the hole transport material. The nearly cubic crystal structure and appropriate band gap render this new FAPbI₃ perovskite extremely attractive for next generation high-efficiency low-cost solar cells.
