(Organic) Electronics for energy transport and harvesting
The Advanced Materials program is world leading in organic photovoltaic, OPV, research, both in unraveling the fundamental working mechanism and in applied studies, with a series of world record efficiencies. Synthetic highlights include the first semiconducting diblock-copolymer, and fullerene bisadducts. Seminal fundamental work includes: unraveling the origin of the ‘open-circuit voltage’ and other important findings in device physics and modeling; study of charge transport including demonstration of several interesting systems for ambipolar field effect transistor and solution processed ferroelectric field effect transistors; ultrafast spectroscopy studies on charge generation and separation importantly, the works on charge transfer states and their importance in the working mechanism of organic solar cells have been seminal for the field. Organic and hybrid photovoltaic world records include 3.5% power (in 2003) conversion efficiency, plastic solar cells and a 5.2% power conversion efficiency in a PbS-nanocrystal cell (in 2013). The broadband dye-sensitized upconversion has been also investigated employing a hybrid approach. This line of research has been strongly supported by a FOM funded Focus group on Next Generation Organic Photovoltaics.
