Optimising Absorption in Luminescent Solar Concentrators constraint by Average Visible Transmission and Color Rendering Index

The luminescent solar concentrator (LSC) as energy harvesting window is an emerging technology in the realm of building integrated photovoltaics. Using recent advancement for assessing balance between transmitted color quality and potential electricity generation, this paper optimizes theoretical luminophore absorption spectra highest power generation possible. conversion efficiencies (PCE) are based on coupling LSC waveguide to a highly efficient crystalline silicon cell. A non-convex optimisation algorithm maximizing used with constraints parameters: average visible transmission (AVT) rendering index (CRI). An optimal has been defined using continuous function cut-off limited spectrum. Two types set: 1) 55% < AVT 100% 2) 70 CRI 100. first constraint will ensure sufficient light second ensures appropriate rendering. Ray-trace validated results show high ranging from 9.53% 14.3% (AVT = 90%, 98) 55%), respectively. Future studies can use these benchmark (tandem) LSCs specific lighting requirements. Furthermore, flexibility proposed method allows adaptation not paper.
