Photovoltaics: The Complete In‐Gap Electronic Structure of Colloidal Quantum Dot Solids and Its Correlation with Electronic Transport and Photovoltaic Performance (Adv. Mater. 6/2014)

Abstract

Surface defects, acting as traps for charge carriers, are a key factor limiting the performance of colloidal quantum dot (CQD) photovoltaics. Revealing the full electronic band structure of PbS CQD devices, subjected to the latest surface passivation treatments, enables a direct correlation of features in the band structure with device performance characteristics, as described by Osman M. Bakr and co-workers on page 937.
