In China, CGTN reported that a team of Chinese researchers has achieved a record solar hydrogen production efficiency of 10.36%, sustained for over a month, paving the way for large-scale green hydrogen production.
According to a study recently published in Nature Communications, researchers from the University of Science and Technology of China and Wuhan University designed a novel photoelectrode structure using silicon-based gallium nitride nanowires to achieve this breakthrough, the report stated.
The structure delivers high solar hydrogen production efficiency in a half-cell configuration, with stable hydrogen production for over 800 hours at high current densities. It also extends the photoelectrode’s service life from hours to months, overcoming the efficiency and reliability challenges traditional photoelectric hydrogen production devices face, according to the study.
