Commercially available solar selective coatings are primarily used in solar thermal applications, where they enhance the efficiency of solar energy conversion by selectively absorbing sunlight while minimizing heat loss.
Solar thermal selective coatings (STSCs) are crucial for enhancing the thermal efficiency of receivers in solar power applications. Enhancing the photothermal conversion performance of STSCs is crucial for improving the thermo-economic efficiency of these sustainable high-temperature applications.
Electroplated coatings are the most widely used coatings in the solar collector industry. These coatings are applied to the absorber plate metal using traditional electroplating technology.
To achieve metal/ceramic solar selective coatings with super thermal stability at high temperature for a long term, one route is to modify the substrate through depositing a barrier layer, forming a surface oxidation on stainless steel, or choosing nonmetallic substrate to eliminate the diffusion of substrate element.
Ceramets are the most used selective coatings in solar PTCs. Sandia National Laboratories is currently researching solar selective coatings for tower systems to improve their optical properties . Various coatings have demonstrated absorptivity exceeding 90% at temperatures of 600 °C and 700 °C [28, 29].
The real spectrally selective solar absorber coating should have certain properties such as: high solar absorptance of α ≥ 0.950 (0.25–2.5 µm), very low thermal emittance of ε ≤ 0.10 (1–25 µm) and high thermal stability at elevated temperatures (T ≥ 565°C) (Zhang et al., 2017).
