Presentation Title
Investigation of Nanoparticle Ligand Systems for Solar Cell Applications
Abstract
Over the past several years, interest in nanoparticle-derived solar cells has increased. This is due to their low material cost, high-potential efficiency, and desirable and tunable optical properties. Using biphasic ligand exchanges, sodium 3-mercapto-1-propanesulfonate (MPS) and sodium 2-mercaptoethane-sulfonate (MES) were successfully exchanged as ligands with oleic acid to create particles that have a higher propensity to move charge in a solar cell. MES and MPS were chosen as ligands due to being shorter and less insulating than oleic acid. The initial as-synthesized CdSe-OLA, and the nanoparticle products of the two ligand exchanges were confirmed by 1H NMR, UV-Vis, and FTIR spectroscopy. These three nanoparticle products were used to synthesize thin-film solar cells characterized by a potentiostat under a halogen lamp.
