Photoelectrodes

SnWO4 thin film photoelectrodes for solar water splitting Solar water splitting offers a solution for solar energy storage problem, since the generated hydrogen can be stored as a renewable fuel. However, a suitable photoelectrode material for water oxidation reaction is still elusive. The reason for this is that the semiconducting materials have to meet the stringent requirements. For example, the elements of the electrode have to be earth-abundant and allow stability in aqueous solution. Furthermore, the photoelectrode has to absorb most of the visible spectrum of the sun to ensure a high solar-to-hydrogen efficiency. In this work, a new promising n-type semiconductor α-SnWO4 was examined.Read More →
