✦ Synopsis

In this paper the phenomena which limit the performance of concentrator cells are examined. These include contact grid shadowing, reflective losses, series resistance and recombination mechanisms. These phenomena are examined individually to determine whether and how their effects on cell performance can be reduced or eliminated. It is concluded that, contrary to popular belief, a significant improvement in cell efficiency may yet be realized. Efficiencies approaching 30% under air mass 1.5 illumination at 300 suns appear to be feasible with properly designed cells. One such possible cell design is proposed.
