Can we truly achieve standalone light-rechargeable energy storage devices without relying on solar cells? Current technologies that integrate solar cells with batteries for storing solar energy face challenges, often requiring additional electronics to match the voltage outputs of solar cells with the input needs of batteries. This results in increased costs, energy losses, and bulkiness, making them unsuitable for applications like advanced on-chip smart devices and off-grid mini-scale systems.

Our research aims to push boundaries, foster new ideas, and open new fields by developing innovative solutions to these challenges, enhancing our lives through the effective use of green solar energy. Some battery materials exhibit semiconductive properties and generate photocurrent when exposed to light. We explore the interaction between light and semiconducting battery materials during the charge storage process and design photoelectrode materials that facilitate efficient charge transfer. These systems can operate in a "photo-accelerated" mode, allowing for faster charging and continuous power generation, even during discharge under light illumination.
