Nanoparticle-based materials are frequently utilized in a variety of applications such as drug delivery, energy production, and catalysis. The shape, composition, and size of nanoparticles has a significant influence on their performance, so producing controllable manufacturing systems is crucial to the commercialization of the latest nanomaterials.

Despite the progress in perovskite device efficiencies, these systems are not fully understood, in particular the frequency- and power-dependence of their response to light. Yu-Hwa Lo and colleagues at the University of California in San Diego (UCSD) now report on systematic investigations of how these devices respond to light for frequencies varying over eight orders of magnitude and power ranging from millions to single photons.
