Abstract
A solar collector is formed as a compound arrangement of a multiple number of tapered, pyramidal-type structures. This forms an N-stage solar collector, each stage providing a degree of concentration and thus forming an arrangement that is smaller than a single stage collector (while achieving the same amplification factor). The stages are arranged in tandem along a common optical axis, with the output of the first stage becoming the input for the second stage, and so on. It was found that a reduced number of reflections is required, reducing the loss of the overall system.
