Résumé

We studied the influence of the ligands on the optical properties of PbS QD solids using the photoluminescence spectra and the kinetics of photoluminescence decay. As the ligand molecule length decreases, the photoluminescence decay becomes faster, which in a good agreement with the theory of the hopping mechanism of charge transfer in QD solids. We also fabricate photovoltaic structures (ITO/PEDOT:PSS/PbS/ZnO/Al) based on PbS QD solids and investigate the influence of various organic ligand molecules on its photovoltaic characteristics. The maximum efficiency was observed in samples with a ligand of intermediate length.
