Current approaches for electric power generation from nanoscale conducting or semi-conducting layers in contact with moving aqueous droplets show efficiencies of around 30 percent but pose challenges regarding fabrication and scaling. Stable all-inorganic single-element nanolayers prepared in a single step are reported here that generate electrical current when aqueous solutions flow along their surface. Mechanistic insights derived from theory and experiments are discussed.
