Temperature dependent behaviour of lead sulfide quantum dot solar cells and films
Mark J. Speirs,Dmitry N. Dirin,Dmitry N. Dirin,Mustapha Abdu-Aguye,Daniel M. Balazs,Maksym V. Kovalenko,Maksym V. Kovalenko,Maria Antonietta Loi +7 more
TL;DR: In this article, the authors explore the temperature dependent behavior of ∼9% efficient solar cells and find increased VOC and FF values without significant degradation of the short circuit current, leading to up to 10.3% efficiency at 230 K.
Origin of the increased open circuit voltage in PbS–CdS core–shell quantum dot solar cells
Mark J. Speirs,Daniel M. Balazs,Hong-Hua Fang,Lai-Hung Lai,Loredana Protesescu,Loredana Protesescu,Maksym V. Kovalenko,Maksym V. Kovalenko,Maria Loi +8 more
TL;DR: In this article, the authors demonstrate solar cells made from PbS-CdS core-shell QDs, yielding a 147 mV increase in VOC compared to core-only QDs.

TL;DR: In this paper, the authors reported high performance field effect transistors based on lead-sulfide colloidal quantum dots (PbS CQDs) crosslinked with 3-mercaptopropionic acid (MPA).

TL;DR: In this work, effective coating of PbS CQDs with fluoride ligands is demonstrated and compared to the results obtained with other halides, leading to a relatively more pronounced p-type behavior of the fluoride- and chloride-treated films compared with the iodide-treated ones.
