Location: Faculty Seminar Room


In the last decade perovskite nanocrystals (NCs) burst into the scientists’ consciousness as a new class of semiconductors and became the materials in forefront of research efforts. The first efforts1-3 and followers4-10 showed the great potential of perovskites as absorbing layer in photovoltaics and have triggered numerous fundamental studies of their features.11-13 These materials are of enormous interest due to their intriguing optoelectronic properties such as high quantum yield without surface passivation14 and narrow emission line widths. One of the most striking features of them is their high tolerance towards defects.15 Also, the pioneer work by Kovalenko and coworkers displayed a practical colloidal synthesis procedure at low temperatures for the formation of perovskite NCs.16  This simple method opened new horizons for the fabrication of perovskite nanomaterials with different morphologies, by adjusting their composition and the synthesis’ temperature.17-20
