Researchers at China's Tianjin University have achieved a milestone in solar-powered hydrogen production, developing a semi-transparent photoanode that pushes solar-to-hydrogen (STH) conversion efficiency to a record 5.1 percent.

The breakthrough, published in Nature Communications, offers a promising pathway for scalable "artificial leaf" technology, reported Science and Technology Daily on Tuesday.

"Artificial leaves" are silicon-based devices using solar energy to split hydrogen and oxygen in water, thereby producing hydrogen energy in a clean way.

Led by Wang Tuo, a professor from the School of Chemical Engineering and Technology, the research team addressed critical limitations in unbiased solar water splitting systems, which produce hydrogen without external voltage.

Their innovative indium sulfide (In₂S₃ ) photoanode overcomes the traditional trade-off between conductivity and light transparency...more

Anyone looking at H2 for ANYTHING knows the future is China, not the United States of Arrogant Warmongers - where Donald Dump has decided that he wants Coal and hates hydrogen.
