The present paper investigates the Luminescent Solar Concentrator (LSC) with single and dual waveguide coated with perylene dye of various concentrations. Monte Carlo simulations are carried out to assess the efficiency of the LSC with the waveguide areas varying from 10 to 110 cm 2 , and the dye concentration varying from 30 to 800 PPM. The percentage of dye area coated in the waveguides is varied from 20 to 80%. Results indicate that the LSC efficiency increases with dye concentration up to a

Experimental and simulation results indicate the maximum efficiency at the dye coverage area of 50%. Simulation results indicate the maximum LSC efficiency of around 9%, while the same is around 6% when examined experimentally. 241 LSC efficiency. Further, dual patterned waveguides are considered and compared with single pattern waveguide. Experiments are carried out with the waveguides to support these simulation results.
