Photo-rechargeable batteries can implement solar energy harvesting and storage simultaneously and have attracted strong interest from researchers.The development of photoactive electrodes is the key to pro-moting the development of high-performance photocells.Herein,a free-standing BiOI@MWCNTs film is developed as photoelectrode to achieve the effective separation of photogenerated electron-hole pairs for high-efficiency solar-electric-chemical energy conversion.Light can charge up photocells with a photo-conversion efficiency of～1.3％,as well as accelerate charge transfer without requiring any external bias voltage.Ex situ XRD and XPS tests prove that the enhanced electrochemical reaction kinetics can improve the chemical-electric energy conversion efficiency under illumination.The capacity of the proposed pho-tocell can be increased by 10.6％(from 195 mA h g-1 to 216 mA h g-1 at 0.2 A g-1)and 57.9％(from 76 mA h g-1 to 120 mA h g-1at 5.0 A g-1)in light condition,while exhibiting a cyclic life of up to 600 cycles.This work can help to deepen the understanding of photo-rechargeable batteries.
