Efficiently turning light into electricity

Perovskites form a group of crystals that have many promising properties for applications in nano-technology. However, one useful property that so far was unobserved in perovskites is so-called carrier multiplication -- an effect that makes materials much more efficient in converting light into electricity. New research performed in collaboration between the University of Amsterdam and Osaka University has now shown that certain perovskites in fact do have this desirable property.
