Solar thermal technology offers a promising solution to water scarcity; however, the continuous operation of solar evaporators remains challenging due sunlight's intermittent availability. Herein, an alternative strategy is proposed achieve dual-functional energy management photo-thermoactivated viologen T semiconductors for enhanced evaporation, water-enabled electricity generation, and electrothermal evaporation. A sequential cyanide-bridged layer-directed intercalation approach developed, where infinitely π-stacked, redox-active N-methyl bipyridinium cations with near-planar structures are sandwiched between MnII-FeIII. The extended absorption range 95% achieved through radical-π interactions that occur within continuously π-stacked units upon activation. MnII-FeIII compounds anchored charcoal mask (MnII-FeIII@CM) sided evaporation structure controllable transfer, offering high rate 2.39 kg m-2 h-1 under one sun (1 kW m-2) illumination. As nanogenerator, output voltage current MnII-FeIII@CM can reach up ≈480 mV ≈60 µA cm-2 ambient conditions. Furthermore, storage electrical from using devices expected enable all-weather by electric heating unsustainable sunlight, providing unique seawater desalination offshore work platform access.
