- •
Thermal performance of high temperature spectrally selective absorber coating (α=0.956, ε=0.07).
- •
High temperature experimental emittance measurements for the coating in the range of 100–500 °C.
- •
Theoretical efficiency modeling of STEG coupled with the selective absorber:predicted efficiency of 9.3% at 300 °C hot side temperature in vacuum.
- •
Experimental performance of natural air cooled STEG coupled to selective coating and 3 commerical Bi2Te3 TE modules.
- •
Output power of 660 mW and efficiency of 1.2% obtained at 280 °C under optical concentration ratio of 62.
