Thermally integrated PV-electrolyzer with 9.1% solar-to-hydrogen efficiency – pv magazine International

A Swedish research group has developed a device combining CIGS thin-film solar modules and an alkaline electrolyzer based on a trimetallic cathodic catalyst made of nickel, molybdenum, and vanadium (NiMoV) and an anode made of nickel oxide (NiO). The electrolyzer achieved an average solar-to-hydrogen (STH) efficiency of 8.5% for stable operations during 100 hours.
