Fullerenefreie Solarzelle

New molecules for cheap solar power

Jülich, 21.11.2016 – An international team of scientists from Imperial College London, King Abdullah University of Science and Technology (Saudi Arabia), Stanford University, Friedrich-Alexander Universität Erlangen-Nürnberg, Hongkong University of Science and Technology and Forschungszentrum Jülich have developed organic solar cells with increased photocurrent and open-circuit voltage. These solar cells use novel acceptor molecules that are not based on the traditional fullerene molecules that have been prevalent for the last 20 years in organic photovoltaic research. The new acceptor molecules have a range of advantages relative to fullerenes: They absorb light more strongly are easier to synthesize, their energy levels can be fine-tuned easily and their stability is strongly enhanced relative to fullerene based solar cells. The research on non-fullerene acceptors was recently published in the Journals Nature Materials (DOI: 10.1038/NMAT4797) and Energy and Environmental Science (DOI: 10.1039/c6ee02598f).
