The effects of shape and photovoltaic cell placement on efficiency are studied for luminescent solar concentrators. The mean path length of light rays is found to be a poor measure of performance. Simple arguments based on a method of images show that the efficiency grows linearly with detector size h, saturating at h ≈ πA/λ, where A is the captation area of the collector, and λ is the attenuation length of radiation in the medium. Monte Carlo simulations confirm that efficiency is relatively independent of collector geometry.
