Riassunto
Lo scopo di questa tesi è quello di investigare le performance di dispositivi accoppiati costituiti da un concentratore solare luminescente (LSC) e una cella solare. La prima parte del progetto si concentra sulla caratterizzazione di LSC da fluorofori innovativi. Questi ultimi sono stati dispersi in due diverse matrici polimeriche, il convenzionale poli(metil metacrilato) e il poli(cicloesil metacrilato) come possibile alternativa. Gli LSC sono stati costruiti nella configurazione a film sottile e le loro performance sono state valutate tramite caratterizzazione spettroscopica (spettri UV-Vis e di fluorescenza, resa quantica) e misure di efficienza ottica. Nella seconda parte, ingegneria composizionale e tecniche di deposizione innovative sono state usate per costruire celle solari in perovksite ad ampia area, da accoppiare a LSC preparati con il fluoroforo dello stato dell’arte, il Lumogen Red.
The main goal of this thesis is to investigate the performance of coupled devices made of a luminescent solar concentrator (LSC) and a solar cell. The first part of the project focuses on the characterization of LSCs from innovative fluorophores. These latter ones were dispersed in two different polymeric matrices, the conventional poly(methyl methacrylate) and poly(cyclohexyl methacrylate) as a possible alternative. LSCs were built with the thin film configuration and their performances were evaluated via spectroscopic characterization (UV-Vis and fluorescence spectra, quantum yield) and optical efficiency measurements. In the second part, compositional engineering and innovative deposition techniques were used to build large area perovskite solar cells and couple them with LSCs made with the state-of-the-art fluorophore, Lumogen Red.
