A limiting factor of the power conversion efficiencies of organic photovoltaic devices is low voltage output. Methano derivatives of the trimetallic endohedral fullerene Lu3N@C80 have now been synthesized and used as the acceptor in organic photovoltaics. The open circuit voltage of the devices is significantly above those made using alternative fullerenes.
