Monte Carlo Raytracing of a Luminescent Solar Concentrator

Photons are propagated through a rectangular shaped LSC using the monte carlo method.

The Monte Carlo technique is a statistical approach to modelling propagation of photons through a system. Random numbers, cumulative distribution functions (CDFs) and probability density functions (PDFS) are used to sample from functions or spectra such as the solar AM 1.5. In this way the random number determines the fate of the photon and complex radiation transfer equations can be avoided. The number of photons emitted at each surface is noted and in this way the optical efficiency of an LSC can be estimated.
