Development of Inorganic Monolithic Devices for Photovoltaic Energy Conversion and Storage
The goal of my thesis is the development and characterisation of inorganic monolithic devices for photovoltaic energy conversion and storage with a special focus on perovskite-based inorganic photovoltaic cells. Together with my colleagues Dr. Taisiia Berestok and Jan Büttner and in collaboration with the team of Dr. Jan Christoph Goldschmidt at Fraunhofer ISE, I am working on integrating these cells with batteries and supercapacitors to create monolithic SolStore devices in a three-electrode configuration. These convert light into electrical energy, which they can store in situ and release at a later stage to power small electrical consumers.
