Efficient Production of Solar Hydrogen Through Direct Coupling of Concentrating Solar Cells and Electrolyzer

Splitting hydrogen from water molecules via electrolysis requires energy, which ideally comes from renewable energy sources. Scientists at the Fraun-hofer Institute for Solar Energy Systems ISE have developed a combined pho-tovoltaic/electrolysis module that efficiently produces hydrogen directly from solar energy. To do this, the water molecule is split using the high photo-voltage of…
