The ad hoc Team on Perovskite PV Cells of NIMS GREEN succeeded in producing highly reproducible and highly stable perovskite solar cells by a low-temperature solution process. The results were published in the June 14, 2015, issue of Journal of Materials Chemistry A, a journal issued by the Royal Society of Chemistry, UK
Schematic of the perovskite solar cell developed in this research and a scanning electron microscope image of its cross-sectional view (left) and output characteristics (right)Light is absorbed in the perovskite layer, and electrons and holes (charge carriers) generated by photoexcitation are transported— electrons to the electron transporting layer (PCBM) and holes to the hole transporting layer. Then, they are extracted from the electrode, generating electric power with the output characteristics as shown on the right.
