In article number 1908762, Haiguang Zhao, Zhiming M. Wang, Federico Rosei, and Gurpreet Singh Selopal report on colloidal core/shell quantum dots (QDs) that exhibit promising optical and electrical properties. The recent developments in the engineering of the structure of core/shell QDs to tune exciton dynamics so as to improve the performance of QDs sensitized solar cells are presented.
Semiconductor nanocrystals, the so‐called quantum dots (QDs), exhibit versatile optical and electrical properties. However, QDs possess high density of surface defects/traps due to the high surface‐to‐volume ratio, which act as nonradiative carrier recombination centers within the QDs, thereby deteriorating the overall solar cell performance. The surface passivation of QDs through the growth of an...
