With the research activity reported in this Ph.D. thesis, I provided to photovoltaic issues the following contributes: 1.Research and development of a facile synthesis of semiconductor nano-structures, with proper morphologies and shapes to provide efficient radiation harvesting for solar cells. Moreover, it has been undertaken an examination of novel nano-structures geometries and the related light-matter interactions. 2.Investigation of some key features of physical and chemical deposition methods, suitable for the synthesis of cuprous oxide thin films for cheap and green solar cells. Since the efficiency of Cu2O based hetero-junctions has not yet surpassed 6% [9], it has been also endeavored to improve the material properties by means of doping with a wide variety of non-toxic and Earth-abundant elements.

Con l'attività di ricerca, riportata in questa tesi di Dottorato, ho fornito, alle questioni concernenti il fotovoltaico, i seguenti contributi: 1.Ricerca e sviluppo di un semplice metodo di sintesi di semiconduttori nanostrutturati, con una morfologia particolarmente adatta all'assorbimento efficiente di radiazione per le celle solari. Inoltre, è stato intrapreso lo studio di innovative geometrie e le relative peculiari interazioni con la luce. 2.Analisi e confronto dimetodi di deposizione fisici e chimici per la sintesi di film sottili di Cu2O, per applicazioni nel fotovoltaico. Poichè l'efficienza delle celle solari, a base di Cu2O, non hanno , ancora superato il 6%, parte di questo lavoro è stata dedicata al miglioramento delle proprietà fisiche del materiale per mezzo di doping.

Abstract
With the research activity reported in this Ph.D. thesis, I provided to photovoltaic issues the following contributes: 1.Research and development of a facile synthesis of semiconductor nano-structures, with proper morphologies and shapes to provide efficient radiation harvesting for solar cells. Moreover, it has been undertaken an examination of novel nano-structures geometries and the related light-matter interactions. 2.Investigation of some key features of physical and chemical deposition methods, suitable for the synthesis of cuprous oxide thin films for cheap and green solar cells. Since the efficiency of Cu2O based hetero-junctions has not yet surpassed 6% [9], it has been also endeavored to improve the material properties by means of doping with a wide variety of non-toxic and Earth-abundant elements. In particular, the doping has been fulfilled employing deeply different approaches.File | Dimensione | Formato | |
