Then, the state-of-the-art progress for photothermal conversions of solar energy is introduced in detail, mainly including photothermal water evaporation and desalination, photothermal catalysis, photothermal electric power generation, photothermal bacterial killing, photothermal sensors, and photothermal deicing.
Although photothermal electric power generation can show a solar-to-electricity conversion efficiency exceeding 7% under 38 Sun, its conversion efficiency remains very low under low concentration solar intensity, such as 1 Sun or ambient conditions.
Solar-driven photothermal materials are promising platforms for addressing global energy challenges and environmental issues. Solar energy mainly focuses on the wavelength range from 300 to 2500 nm (Figure 3a), which occupies over 98% of solar energy.
Among all the solar energy conversion technologies, photothermal conversion of solar energy exhibits unique advantages when applied for water purification, desalination, high-temperature heterogeneous catalysis, anti-bacterial treatments, and deicing.
