Summary: Materials and methods for solar thermal and photovoltaic applications of solar energy are investigated. The methods and materials for thermal and electrical energy storage are studied. The effects of temperature on various solar cells were investigated. The photovoltaic system has been analyzed in order to improve it's conversion efficiency. The characteristic parameters of the system were estimated. Computer simulations of solar system performances in various region of Croatia are performed. The importance of using regionally modified correlations is established. The values of the modified utilizability function are determined for our climatic region. The performances of monocristalline and amorphous silicon and GaAs solar cells are compared and the influence of device parameters on the system performance is discussed.

Keywords: Solar energy, solar radiation, global and diffuse radiation, thermal conversion, photovoltaic conversion, photovoltaic system, energy storage, solar cells, simulation, optimization, utilizability functions

Research goals: Goals of the project are to improve solar conversion efficiency, particularly in photovoltaic applications, to develop regional correlations for system performance evaluation, and to study the influence of various parameters on the system performance. By developing methods for the simulation of the photovoltaic work and modeling it's components, it is possible to estimate energy flow through the system and it's optimal work. In order to perform system evaluation, various empirical correlations are to be developed.Comparative study of various systems are to be performed.
