open-source ray tracing software capable of simulating a variety of 3D geometries, conducting validation studies on planar and wedge-shaped LSCs with scattering phosphor films. However, the most widely used open-source ray tracing software for LSCs is pvTrace, which has previously been used to model rectangular LSCs and cylindrical/fiber LSCs. It has also been used to study more unconventional geometries, such as luminescent solutionfilled cuvettes, 71 luminescent photo-microreactors, LSCs with aligned nanorods, the electric mondrian TM , and PV leaf roof tiles. pvTrace has been validated against other models of LSCs, including the thermodynamic model, the ray-tracer developed by Burgers et al., and the ray-tracer developed by Kennedy et al., as well as against experimental results. Despite the versatility of pvTrace, it still contains some inherent limitations. First, the code is relatively inflexible in terms of photon output emission counting, as only the position of each exit photon is known and not which face the photon is exiting from. Further, the code is relatively slow, as it is serialized to model one photon at a time, and simulations of geometries with many curved surfaces can be inefficient to run. Finally, although the code is open-source and welldocumented, it still requires a level of programing knowledge in to obtain useful results.
