Innovative Solar Power (ISP) has developed a quasi-static solar concentration system that combines theadvantage of high power conversion of concentrating systems with low cost of static installations withoutexpensive sun tracking elements. The estimated cost of such system is equal to 25% of price of today's typicalinstallations. The company has spent as far approximately $1M to develop this new technology, to fabricateprototypes and to demonstrate the potential of their concept. However, in order to commercialize ISP systems,it is necessary to evaluate their reliability, since this parameter is fundamental for comparison with standard PVtechnology in terms of investment's profitability estimation. In this project, we will study the reliability of thesilicon solar cells, which are important components of the system. Since the receiver, with its silicon photoconverter, are in the focal axis of the concentrating mirrors, they will be exposed to a high temperature.In this project we will investigate the effect of temperature on the system performance and its impact on solarcells aging and on ISP system performances.
