Researchers have demonstrated that single dopant atoms in tungsten diselenide bilayers act as elementary photovoltaic units, generating nanometer-scale photocurrents through localized field effects rather than traditional bulk junction mechanisms. This discovery establishes a fundamentally new charge separation process at the atomic scale where excitons are split by individual impurities independent of illumination power or density. Such findings advance our understanding of light-to-electricity conversion in 2D materials, offering pathways for next-generation quantum photovoltaic devices and ultra-small optoelectronic components.
