A Photo-assisted Rechargeable Battery: Synergy, Compatibility, and Stability of a TiO/dye/CuS Bifunctional Composite Electrode

Herein, we present a simple and novel approach to fabricate a bifunctional compatible electrode, which has functionalities of photoelectric conversion and energy storage. The integrated photo-assisted rechargeable battery of the two-electrode system demonstrates potential reduction and impressive performance enhancement with the assistance of illumination. Such a structure of a bifunctional compatible electrode provides more possibilities to develop more practical photo rechargeable battery.
