Paper Abstract

The importance of renewable energy sources is currently attracting widespread attention due to the limited availability of fuels and major environmental impacts. A great deal of effort is put our days on the development of new efficient solar energy collectors either by quantum or thermal conversion. On this communication we will refers just to thermal converters focusing on the roughness and microtopographic inspection of surface thin films and spectrally selective coatings. Physically Vapor Deposited coatings like sputter deposited metal oxide and nitride thin multilayered and graded ones can be used in spectrally selective surfaces for thermal collectors and energy- efficient windows.
