Abstract:
This talk highlights projects at UC Irvine to develop thin-film photovoltaics based on earth-abundant iron pyrite (FeS2) active layers and PbSe/PbS quantum dot (QD) solids. I will first introduce the promise and challenge of pyrite, describe solution- and gas-phase syntheses of pyrite films, and present preliminary electrical characterization of pyrite layers and device stacks. Then I will switch gears to discuss several projects focused on the chemistry/physics of QD solids, particularly our efforts to produce environmentally robust PbSe QD films with very long carrier diffusion lengths for next-generation solar cells. |
