Abstrakt: Here, we present a new two-electrode photo-rechargeable FTO/TiO2/Cs3Bi2I9/Pt/FTO system. The key material is the photoactive lead-free perovskite Cs3Bi2I9, which performs photoelectric conversion and provides energy storage. This study is the first example of a battery system in which charging and discharging are based on bismuth redox chemistry. In the photo-charged state, the fabricated battery has an open-circuit voltage of ~0.28 V in the dark. With a series-connected pack of these batteries, an LED was lit for tens of seconds in the dark.
