Abstract
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 cm2, 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 particular value, and thereafter shows a decreasing trend. Further, LSC efficiency is found to be increasing with a decrease in waveguide size. 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.

Solar energy is the sustainable source of energy besides the other energy resources like oil, coal, natural gas, and biomass
The results show that the Luminescent Solar Concentrator (LSC) efficiency is maximum at a dye concentration of 38.65×10-3 mol/l
LSC efficiency is observed to increase with dye concentration
Summary
Solar energy is the sustainable source of energy besides the other energy resources like oil, coal, natural gas, and biomass. It is understood that only a fraction of solar energy reaches the earth surface [1]. Harvesting solar energy can partly satisfy energy demands and overcome environmental problems. Photovoltaic (PV) cell is a solar device which converts solar radiation directly into electricity. Silicon is the most commonly used material for PV cells. PV cells are categorized as first, second, and third-generation depending upon the material and structure. First-generation PV is made of doped silicon while the second-generation uses thin-film technology. Third-generation PV utilizes the concept of multi-junction cells that are the most efficient cells developed with efficiencies above 40%. Commonly produced PV cells include polycrystalline silicon, amorphous silicon, and thin-film silicon
