Highly charged solar evaporator toward sustainable energy transition for in-situ freshwater & power generation

Highly charged solar evaporator for in-situ freshwater and power generation excluding volatile ammonia using Donnan exclusion strategy by optimizing positive charge density. The multi-functional solar evaporator yields ∼14.66 kg m−2 freshwater from wastewater, and the complementary thermoelectric generator achieved a power density of ∼45.4 Wm−2 along with solar to electric conversion efficiency (γ = 2.27%).
