Luminescent Solar Concentrators (LSCs) are optical devices based on a polymeric panel doped with a fluorophore, which is capable to improve the photovoltaic efficiency of a typical PV cell, at the edge of the panel, reducing the costs of installation and materials. Organic compounds will be promising dyes for LSC application for their versatile spectroscopic characteristics, depending on a specific structural design. This work is focused on fluorescent organic compounds with a typical conjugated D-A-D structure. New dyes were synthetized and characterized spectroscopically in solution and in polymer matrix, such as PMMA. All the dyes showed good spectroscopic characteristics, in particular the optical efficiency which is in a range of 8-11% for all derivatives, higher than the typical commercial reference, Lumogen Red 305 (7.4%) at the same concentration (1.4%).

Abstract
Luminescent Solar Concentrators (LSCs) are optical devices based on a polymeric panel doped with a fluorophore, which is capable to improve the photovoltaic efficiency of a typical PV cell, at the edge of the panel, reducing the costs of installation and materials. Organic compounds will be promising dyes for LSC application for their versatile spectroscopic characteristics, depending on a specific structural design. This work is focused on fluorescent organic compounds with a typical conjugated D-A-D structure. New dyes were synthetized and characterized spectroscopically in solution and in polymer matrix, such as PMMA. All the dyes showed good spectroscopic characteristics, in particular the optical efficiency which is in a range of 8-11% for all derivatives, higher than the typical commercial reference, Lumogen Red 305 (7.4%) at the same concentration (1.4%).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
