Summary / Abstract: This study presents a novel configuration for luminescent solar concentrator photovoltaic (LSC-PV) devices using a mixture of multiple organic luminophores namely, Perylene Green, Lumogen Red 305, and Lumogen Orange 240. This LSC-PV device includes a cubical lightguide with a dimension of 10× 10×10 mm3 and made of poly (methyl methacrylate) (PMMA), containing a mixture of two or three perylene dyes. The mono-crystalline silicon bifacial solar cells (mono c-Si) are mounted on the edges and bottom sides of this device. This study evaluates the optical efficiency (OE) and power conversion efficiency (PCE) of four different configurations of LSC-PV devices with variations of mixed luminescent dyes in order to obtain the highest performance and optimal structure for the combination of dyes. For this purpose, a Monte Carlo ray tracing simulation is conducted in LightTools software to explore the effect of multiple luminescent dyes on the optical performance of LSC-PV devices and analyse the incident irradiance on the front and rear sides of edges- and bottom-mounted bifacial solar cells. The comparison results show that the highest theoretical optical efficiency is 88.2% under standard test conditions (STC) for an LSC-PV device containing a mixture of Lumogen Orange 240 and Perylene Green dye at 10 ppm. The theoretical power conversion efficiency is then 17.7%.
