Accelerated Stress Testing Of Hydrocarbon-Based Encapsulants For Medium-Concentration Cpv Applications, M. D. Kempe, T. J. Moricone, M. Kilkenny, J. Z. Zhang

Publications (E)

Concentrating photovoltaic (CPV) systems have great potential to reduce photovoltaic (PV) electricity costs because of the relatively low cost of optical components as compared to PV cells. A transparent polymeric material is used to optically couple the PV cell to optical components and is thus exposed to the concentrated light source at elevated temperatures. In this work polymeric encapsulant materials are positioned close to a Xenon arc lamp to expose them to ultraviolet radiation (UV) that is about 42 times as intense as sunlight. Furthermore, different glass types are used as filters to modify the spectral distribution of light in …
