Book excerpt: Colloidally synthesized CIS NCs are investigated in this work for their charge transport and charge transfer properties. By post-synthesis removal and replacement of the different types of ligands surrounding the CIS NCs, these properties can found be enhanced - especially by a combination of successive solution-phase and post-deposition ligand exchanges, which is derived from results obtained by measurements in combination with different polymers as active layer blends for BHJ solar cells. An investigation of the charge carrier transport in the CIS NCs by single carrier devices shows a three orders of magnitude larger hole than electron mobility. Regarding the polymers used for the CIS NCs blends, P3HT exhibits generally favorable properties compared to PCPDTBT, such as effective charge transfer processes and more efficient solar cell performances. engl.
