For optimized coatings solar absorptance coefficients a>0.92 and thermal emittance coefficients e<0.1 (400°C) were achieved. These results render CNT coatings as a low cost and high performance alternative to commercially available vacuum deposited cermet coatings for concentrated solar power (CSP) applicationencarbon nanotubesoptically active materialsfunctional coatingsthin filmssolar selective coating621journal article
