Forschungsinteressen

Mein wissenschaftlicher Auftrag und meine Motivation ist es, das Potenzial von Photovoltaik-Technologien der nächsten Generation durch Forschung, Innovation und akademische Ausbildung zu erschließen. Die Forschung meines Teams konzentriert sich auf die Wechselwirkung zwischen Licht und strukturierter Materie mit dem Ziel, neue optische Konzepte, Materialien und Gerätearchitekturen für die kostengünstige Gewinnung von Sonnenenergie zu entwickeln. Wir befassen uns intensiv mit der Herstellung, Charakterisierung, Simulation und dem Verständnis der Gerätephysik von Perowskit-Photovoltaik und Tandem-Photovoltaik auf Perowskit-Basis.

Eine Liste der aktuellen Forschungsthemen finden Sie auf der Webseite meiner Gruppe.

Sie sind herzlich eingeladen, unsere Forschung auf Twitter zu verfolgen.
