摘　　要：With the escalation of industrialization and population growth,energy and clean water shortages pose an unprecedented threat to sustainable development.Therefore,it is imperative to develop green and effective strategies to address these challenges.In this context,solar-driven interfacial water evaporation(SIWE)has emerged as a highly promising low-carbon solution to the water-energy nexus[1].By locating the evaporator at airwater interfaces,heat localization can be achieved,leading to high-efficient water evaporation and freshwater production.More significantly,taking advantage of the special conditions during SIWE has opened numerous opportunities for generation of extra electrical power[2,3].Throughout the processes of SIWE,various elements such as photons,waves,capillary flow,evaporation,vapor motions,condensation,and droplet sliding can all be harnessed to produce electricity through photovoltaic,thermoelectric,thermogalvanic,pyroelectric,piezoelectric,triboelectricity and hydrovoltaic effects[3].Extensive research efforts have provided valuable insights for the development of water-electricity cogeneration(WEG)hybrid systems.
