Abstract

A ray trace model of the light trapping filtered concentrator spectrum splitting architecture is presented. The scripted ray trace allows for examination of non-idealities in materials and design that were not addressed in previous analytical investigations of this optical design. The design of the angle restricting elements is examined with regards to optical efficiency and system efficiency. In addition, the scripted ray trace enables rapid evaluation of multiple candidate filter sets and optimization of the optical design for each set via a gradient ascent algorithm. A discussion of filter design considerations and insight provided by the ray trace model evaluations is presented.
