Projekt

Multifunktionales Energy Harvesting und Speicherung von Solarenergie mit Halogenid-Perowskiten
Ziel meiner Forschung ist es, eine Vorrichtung zu bauen, die gleichzeitig Solarenergie in Ladungsträger umwandeln und als Batterie fungieren kann, die diese Ladungsträger speichert. Dazu ist eine multifunktionale Elektrode erforderlich, die aus einem oder mehreren Materialien besteht. Das Ergebnis wird eine voll integrierte 2-Elektroden-Photobatterie sein.
