a) A simple diagram of the three‐tier device for enhanced steam temperature. b) A detailed description picture of the three‐tier device with enhanced steam temperature. c) The change of steam temperature without heater, with Cu foam as the upper heater and MoS₂@Cu₉S₅‐SA as the upper heater under one sun. d) Percentage increase in steam temperature of with Cu foam as the upper heater and MoS₂@Cu₉S₅‐SA as the upper heater than that of without heater under one sun. e) Steam temperature with MoS₂@Cu₉S₅‐SA under different light intensities. f) Percentage increase in steam temperature with MoS₂@Cu₉S₅‐SA than that of without heater under different light densities.
