Swiss team develops effective and low-cost solar water-splitting device; 14.2% solar-to-hydrogen efficiency

Green Car Congress

The SHJ module captures sunlight and converts it into electricity directly feeding the electrochemical membrane electrode assembly water-splitting unit. A 12-14 m 2 system installed in Switzerland would allow the generation and storage of enough hydrogen to power a fuel cell car over 10,000 km every year. Schüttauf et al. Electrochem.
