While the emissivity of the solar absorber when it coated by using nanoparticles thin films as well as compare the emissivity with energy attained using Stefan Boltzmann law. The increased emissivity when increased and the layers as well as increased spin coating speed from (1000-2000) RPM this improved solar absorber properties. In addition, that increasing emissivity caused decreased the energy attained. ER -
