Abstract
, 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.
