Project R-5178

Novel conjugated material architectures for organic photovoltaics (Research)

Organic photovoltaics (OPV) have emerged as an attractive technology complementary to other types of solar cells. Despite the enormous progress in device efficiency, currently approaching 10% for solution-processed devices, some fundamental principles need to be addressed to be able to take the next step. In the search for new conjugated materials to be used in OPV devices, mostly simple linear polymer structures have been considered. In this project we aim to explore more advanced (branched) low bandgap polymer topologies and their influence on the power conversion efficiency and stability of the resulting solar cells.
