Chinese researchers have pioneered an innovative and reliable semi-transparent indium sulfide photoanode device, marking significant strides in advancing the technology behind "artificial leaves." This device dramatically enhances the rate of water oxidation reactions and the efficiency of solar water splitting for hydrogen production, propelling the development of this cutting-edge technology. By allowing sunlight to penetrate, the device minimizes energy loss and addresses the challenge of photogenerated electron transport. This groundbreaking work offers a promising new approach to tackling energy crises and environmental pollution issues. The findings of this research have been published in Nature Communications.
