Ligand Locking on Quantum Dot Surfaces via a Mild Reactive Surface Treatment

Raffaella Buonsanti, Aurélien Bornet, Anna Loiudice, Ona Segura Lecina

At the outermost surface of colloidal QDs are organic surface ligands which dynamically bind and release in solution to control the growth kinetics, control the size/shape of the crystals, passivate surface states, and provide colloidal stability through f ...

Performance of perovskite solar cells under simulated temperature-illumination real-world operating conditions

Michael Graetzel, Wolfgang Richard Tress, Ulf Anders Hagfeldt, Konrad Domanski, Essa Awadh R Alharbi, Brian Irving Carlsen, Anand Agarwalla

Since reaching 20% efficiency, research in perovskite photovoltaics has shifted from a race for efficiency to a race for stability. For efficiency, the standard test conditions set the rules for the race. However, the term 'stability' is used very broadly ...
