The DFG Research Unit "Printed & Stable Organic Photovoltaics with Non-Fullerene Acceptors" focuses on solar cells made of novel organic semiconductors that can be manufactured using established printing processes. In order to understand and further develop this class of photovoltaic devices from a fundamental perspectivel, the Research Unit takes a strongly interdisciplinary approach and brings together researchers from chemistry and materials science as well as physics and mathematics to printing technology.
