In this thesis work, luminescent solar concentrators (LSC) were obtained by depositing films of carbon dots and PVP-based solutions on glass substrates.

In questo lavoro di tesi, concentratori solari luminescenti (LSC) sono stati ottenuti depositando film di soluzioni a base di carbon dots e PVP su substrati di vetro. Sono state quindi valutate le proprietà ottiche mediante diverse tipologie di analisi tra cui la spettroscopia UV-Visibile e la Fotoluminescenza. Varie soluzioni a base di carbon dots puri e carbon dots dopati con Rame, Manganese e Argento in diverse concentrazioni, sono state testate per osservare eventuali differenze. Le stesse analisi sono state ripetute anche per le soluzioni liquide utilizzate per ottenere i LSC. Ottimi risultati sono stati ottenuti in termini di tempi decadenza ed efficienza, risultando promettenti per sviluppi futuri in ambito fotovoltaico.

Abstract
In this thesis work, luminescent solar concentrators (LSC) were obtained by depositing films of carbon dots and PVP-based solutions on glass substrates. The optical properties were then evaluated by different types of analysis including UV-Visible Spectroscopy and Photoluminescence. Various solutions based on pure and metal-doped carbon dots were tested to observe any differences. The same analyses were also repeated for the liquid solutions which have been used to obtain the LSCs. Excellent results were obtained in terms of lifetimes and quantum yield, showing promise for future developments in photovoltaics.File | Dimensione | Formato | |
