Modeling light propagation in semiconductor-based luminescent solar concentrators

Luminescent solar concentrators (LSCs) convert sunlight to electricity. We study light propagation in LSCs that contain semiconductor nanoparticles. We use radiative transport theory to predict the LSCs’ performance and their optimal design parameters. In particular, a luminescent radiative transport theory is proposed that can take the reabsorption effects into account accurately. The computational results based on radiative transport theory are studied in detail and compared with Monte Carlo simulations for photon transport. The results of this study will aid the development of highly-efficient LSCs.
