Abstract = {{Hybrid nanocomposites (HCs) obtained by blend solutions of conjugated
   polymers and colloidal semiconductor nanocrystals are among the most
   promising materials to be exploited in solution-processed photovoltaic
   applications. The comprehension of the operating principles of solar
   cells based on HCs thus represents a crucial step toward the rational
   engineering of high performing photovoltaic devices. Here we investigate
   the effect of conjugated polymers on hybrid solar cell performances by
   taking advantage from an optimized morphology of the HCs comprising lead
   sulfide quantum dots (PbS QDs). Uncommonly, we find that larger
   photocurrent densities are achieved by HCs incorporating wide-bandgap
   polymers. A combination of spectroscopic and electro-optical
   measurements suggests that wide-bandgap polymers promote efficient
   charge/exciton transfer processes and hinder the population of midgap
   states on PbS QDs. Our linings underline the key role of the polymer in
   HC-based solar cells in the activation/deactivation of charge
   transfer/loss pathways.}},
