The first known Monte Carlo ray tracing study applied to LSCs was in 1983 by Carrascosa et al., in which they simulated a planar LSC composed of a poly(methyl methacrylate) (PMMA) waveguide that was coated with a thin film of PMMA doped with organic dye molecules. The model included basic optical events such as reflection/refraction at LSC faces, waveguide background absorption, and absorption/reemission by the luminophore. Since this work, several other ray tracing softwares have been produced to improve the prediction accuracy and include other effects common in conventional rectangular LSCs. McDowall et al. developed a ray tracing software to include effects of polarization and dye alignment. Kennedy et al. and Şahin et al. expanded the scope of ray tracing software to include quantum dot LSCs. Leow et al. developed a model to include waveguide and polymer host scattering. Several other studies also developed their own in-house Monte Carlo ray tracing software for studying rectangular LSCs. While these studies apply ray tracing to study rectangular LSCs, there has recently been an emergence of ray-tracing programs to simulate unconventional LSC geometries. For example, Kennedy et al. built a ray tracing program to evaluate device performance of rectangular, triangular, hexagonal, and circular LSCs, Hughes et al. compared wedge-shaped to planar LSCs using their own software, while Zhang et al. developed a 3D ray-tracing program to simulate LSCs with bottom-facing PV cells. The plethora of custom-made ray trace codes described above is in part due to the lack of a versatile, open-source, user-friendly software. Many of these purpose-built their ray trace code for a specific purpose and have not published many details about their software. Thus, new studies must start from scratch and write their own code. Some studies opt to use commercial ray tracing software, such as LightTools, GoldSim Pro, or OptisWorks. However, these commercial codes can be expensive and inaccessible for the wider community. Fortunately, there have been some recent efforts in democratizing ray tracing software. Zhang et al. reported an open-source Monte Carlo ray tracing software with a graphical user interface (GUI), increasing the accessibility of such software to those who are unfamiliar with programming by providing a user-friendly interface to model conventional rectangular LSCs.
