The results are important for demonstrating the potential of eliminating traditionally used fullerene-based acceptor materials, which have several drawbacks including high cost, difficulty in production scaling, morphology instabilities and poor light absorption.
"While the best performing organic solar cells continue to use fullerenes, based on our latest results and our current understanding, we believe that in the future non-fullerene acceptors will enable higher efficiencies and better stability than can currently be achieved with fullerene-based cells Such non-fullerene, polymeric acceptors will also be important to tailor the photoactive blend absorption spectrum, which is critical in the rapidly developing field of tandem OPV," Dr. Antonio Facchetti, co-founder and CTO of Polyera, says.
