Abstract
A cover over the absorber of a collector is required to trap the solar radiation through the so called ‘green house effect’. An ideal cover should have maximum transmissivity for solar radiation and must be opaque to the long wave radiation emitted by the absorber plate. The important optical properties that determine the desired characteristics of cover are transmissivity, reflectivity and absorptivity, which are functions of incoming radiation, thickness of the cover, refractive index, and the extinction coefficient of the material. Apart from this the cover should be of low cost, durable, high abrasion resistant, weather resistant, etc.
