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