Effect of Accelerated Thermal Ageing on the Selective Solar Thermal Harvesting Properties of Multiwall Carbon Nanotube/Nickel Oxide Nanocomposite Coatings

Figure 5

Reflectance of the typical selective solar absorber sample before and after thermal ageing test compared to the solar radiation spectrum. From the solar spectrum, absorptance of the sample is calculated. The emittance values as determined from the commercial emissometer are indicated on the reflectance spectra before and after thermal ageing tests.
