Die Umwandlung von Lichtenergie in Strom gewinnt immer mehr an Bedeutung. Technische Fortschritte auf diesem Gebiet hängen wesentlich davon ab, dass es gelingt, die durch Licht erzeugte Energie bei nur minimalen Verlusten zu transportieren. Dafür werden neuartige Komponenten und Bauelemente benötigt. Wissenschaftler der Universität Bayreuth und der FAU Erlangen-Nürnberg berichten jetzt im Forschungsmagazin "Nature" über Nanofasern, die bei Raumtemperatur einen zielgerichteten Energietransport erstmals über mehrere Mikrometer ermöglichen. Dies wird durch einen quantenmechanisch kohärenten Transport entlang der einzelnen Nanofaser gewährleistet.
