Comparison of dispersive and non-dispersive spectrum splitting techniques for photovoltaic systems

There has been a significant interest in spectrum splitting systems to increase the overall efficiency of photovoltaic solar energy systems. In spectrum splitting, an optical system is used to spectrally separate the incident sunlight. Although, systems with different methods and geometries have been proposed, optical systems relying on reflective filters have not been compared to transmissive ones. In this paper, the effects of dispersion introduced by transmission type filters are presented compared to reflective filters.
