Investigation of indoor applications of luminescent solar concentrators under different intensities

A luminescent solar concentrator (LSC) is an optical device that uses light to generate energy. Total internal reflection (TIR) allows it to focus light into certain regions while also collecting direct and scattered light, absorbing photons and reemitting at longer wavelengths. At the locations where the light is focused on the luminophore, one or more solar cells are positioned. As a result, electrical power can be generated. LSCs are created by combining a luminophore such as polymer or glass with fluorescent dye and/or quantum dots. The most common dye in thin film doped LSC applications is Lumogen F Red 305. In this work, an alternate method for creating luminophores is to dope a poly (methyl methacrylate) (PMMA) waveguide with a combination of the dyes Safranin O and Eosin Y. The edges of the luminophore have four monocrystalline silicon solar cells attached in sequence. This thesis work investigates indoor uses. Halogen light sources at twelve various intensity levels, ranging from 90 W/m2 to 350 W/m2, are used to monitor current-voltage (I-V characteristics). According to measurements, the mix luminophore, which is a combination of the dyes Safranin O and Eosin Y, produces the greatest results.
