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.
In fact, the efficiency of current STEC materials is limited by the latter procedure, although the efficient photothermal conversion is often achieved. The main restriction of the effective utilization of the heat by the materials lies in the excessive thermal loss or exchange.
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.
To conclude, photo-thermoelectric power is a promising solar energy conversion technology, but many efforts should be made to improve the solar-to-electricity efficiency, because the efficiency remains still very low based on photo-thermoelectric conversion under AM 1.5 G illumination. [34, 90, 91]
First, four types of fundamental mechanisms of solar-driven photothermal conversion have been summarized, including non-radiative relaxation of semiconductors, plasmonic heating of metals, thermal vibrations of organic molecules and multiple interactions of micro/nanostructured materials.
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.
