    Jan 1, 2021 · Through phenomenological modeling and use of colloidal suspensions as a playground to tune the concentration of the NCs, we distinguish the role of PR and inter-NC EH in PNC films. On a more fundamental level, our method provides a reliable and straightforward way to quantify the exciton transport in nanostructured systems.

    Mar 1, 2017 · Compared to in-situ film growth, films of perovskite NCs have much reduced defects. The QD films fabrication are air-stable, polar-solvent free and reproducible. For their shortcomings, the organic ligands in films will hinder carriers transport and increase carriers injection barriers.
