Setups and their performances of solar vapor generation. (a) Direct contact mode for solar evaporation. (b) Weight loss and (c) evaporation rate of water as a function of irradiation time using different VOPMs in a direct contact mode. (d) Composite device equipped with a thermal insulator and an absorbent paper for solar evaporation. (e) Weight loss and (f) evaporation rate of water as a function of irradiation time using Janus VOPMs with or without the thermal insulator.
