Using the sun's energy, a photoelectrochemical device (PEC), a type of solar cell, can break down water molecules more efficiently than other methods, in order to produce hydrogen. In a new study, the researchers developed a facility that is resistant to corrosion and thus brings us closer to an environmentally friendly hydrogen economy. Source: pixabay.
