Lead halide perovskites: A horse of a different color

Metal halide perovskites have been under intense investigation over the last decade due to the remarkable rise in their performance in optoelectronic devices such as solar cells or light-emitting diodes. Despite tremendous ...

Compositional dependence of perovskite nanocrystal properties

Researchers from Skoltech and Ludwig Maximilians-Universit├Ąt (LMU) in Germany have studied the fundamental properties of halide perovskite nanocrystals, a promising class of optoelectronic materials. Using a combination ...

Perovskites under pressure: Hot electrons cool faster

In solar cells, about two third of the energy of sunlight is lost. Half of this loss is due to a process called 'hot carrier cooling' where high energy photons lose their excess energy in the form of heat before being converted ...
