Abstract

The paper presents the methodology of the analysis of the materials used in solar energy conversion, and an elaborated example with simulations of obtained results. Material properties are selected in relation to the need of sunlight illumination applications in civil constructions. This process is presented , starting from the analysis of some aspects of solar radiation, through the calculations of lens curvature and leading to the execution of simulations in different conditions. Graphical presentation of the phenomenon, it can visualize the process of shaping curves. The materials such as glass, polymers, metals, and gases have been discussed. Particular attention was paid to the results of the transmission of materials, their reflection and absorption of solar radiation. Moreover, the research problems of illumination and reflection in multi-layer structures used for civil constructions have been presented.

/cm. Contact angle measurements were performed according to the sessile drop method [ 29 , 30 ]. Roughness of the modified polymers and thin films was determined with the aid of CCI Theta Lite optical profiler (Taylor Hobson). The surface diversification of polymers was examined by the value of root mean square roughness (Sq) and average roughness (Sa). Scratch resistance of Ag thin films deposited on unmodified and modified substrates was investigated using a Summers Optical’s Lens Coating Hardness Test Kit. For this purpose the abrasion test consisting in rubbing the
