A feature in Sydsvenskan describes Tönu Pullerits' research on perovskites as a material for more efficient solar cells and describes the limitations with the current silicon solar cells. The reason for the feature is that a journal article by Tönu and colleagues has been chosen as one of the best on Perovskites by the Royal Society of Chemistry in Cambridge.
