We hypothesize that this issue may be resolved by replacing the long alkyl-chains with conjugated π-systems, which should increase the electrical conductivity of the NCs. To this end, a new ligand has to fulfil the same requirements as conventional charge transport layers: A match in energy levels for at least one carrier type, if the other is already transported sufficiently well between the NCs, paired with a higher bandgap than the LHP NCs ensures optimal operation.
