Efficiency limits of photovoltaic fluorescent collectors

Abstract
This paper examines the thermodynamic limits of photovoltaicsolar energy conversion by fluorescent collectors. The maximum efficiency of a fluorescent collector corresponds to the Shockley–Queisser limit for a nonconcentrating solar cell with a single bandgapenergy. To achieve this efficiency, the collector requires a photonicstructure at its surface that acts as an omnidirectional spectral band stop filter. The large potential of photonicstructures for the efficiency enhancement of idealized as well as real fluorescent collectors is highlighted.
