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 of critical importance in the rapidly developing field of tandem OPV " said Dr. Antonio Facchetti, co-founder and CTO of Polyera.
