The dye absorbs incident sunlight and re-emits light at a longer wavelength as photoluminescence. A significant portion of the emitted light is directed via total internal reflection to the much smaller edges of the LSC, onto which a strip of PV cells may be attached to collect the light and convert it into electrical current. LSCs can be used in low intensity and diffuse lighting, and offer many advantages for manufacturing and design, such as lightweight and low-cost form factors, as well as customizable colors. These features have led to highly innovative proposals for new applications of LSCs beyond standard PV, which have recently been highlighted. While LSCs are a useful complementary technology to PV, they suffer from optical loss pathways that can limit the amount of incident sunlight that eventually reaches the PV cells (see Figue 1b). For example, most luminophores cannot absorb all the incident sunlight, and the photoluminescence process is also generally not 100% efficient. The waveguide also contributes to several loss pathways, including escape cone losses, re-absorption losses, and parasitic absorption/scattering. Several groups have proposed alternative LSC designs, to both help reduce these optical losses and facilitate incorporation into the built environment. Some examples include cylinders and circles, stacked LSCs, curved LSCs, polygons, wedges, leaf tiles, and mosaic tiles. Reinders et al. also proposed 16 innovative products incorporating LSCs into everyday items. Although it was initially believed that LSC geometry had little effect on the efficiency, many of the these designs have successfully reduced optical losses. As such, there is a need to identify innovative designs that can help improve the efficiency, aesthetics, and functionality of LSCs, to help unlock novel applications. However, fabricating new LSC designs can be time-and resource-intensive. Typical manufacturing techniques either require specific molds to be made for each design or use wasteful subtractive techniques starting from larger stock material. It is therefore highly valuable to be able to quantitatively predict the LSC performance before fabrication, which may be used to inform further design iterations, thus reducing costs and waste.
