a Current–voltage (I–V) curves of the GSt-M device measured under input voltages ranging from 1 to 5 V. b Evaporation performance of the device as a function of input voltage and corresponding input power. Black squares indicate input power, red symbols represent evaporation rates without solar illumination, and blue symbols represent rates under 1 sun illumination. c Infrared thermal images showing surface temperatures of GSt after 2 min at different input voltages (1–5 V), without photothermal heating (left) and with photothermal heating (right).
