N2 - Similar to conventional photovoltaics, the path toward higher efficiencies for luminescent solar concentrators (LSCs) shows increased interest in tandem structures. Herein, a numerical calculation that allows for much faster estimates of fundamental LSC performance indicators (power conversion efficiency, average visible transmission, and color-rendering index) compared to ray trace simulations is proposed. Both double and triple structures are assessed, taking into account concentrations, absorption and emission spectra, and quantum yield as luminophore inputs for rectangular LSCs of any size. The waveguide material is modeled using an absorption spectrum and a refractive index. Interactions between the first, second, and/or third LSCs are incorporated into the algorithm. A comparison with ray trace results shows good correspondence. Supplementary Excel files are available with detailed calculations for future research or industry applications.
