A Photo-rechargeable Aqueous Zinc-Tellurium Battery Enabled by the Janus-Jointed Perovskite/Te Photocathode.

The combination of photo-driven self-powered supplies and energy storage systems is considered as a promising candidate to solve the global energy dilemma. The photo-absorber and the energy storage material are integrated into the photocathode to effectively achieve a high-energy and high-efficiency energy system. In this work, we report the customized -jointed photocathode design (integrating with highly efficient halide perovskite and tellurium composite electrode) and introduce it into the aqueous zinc-tellurium battery.
