Increased Open‐Circuit Voltage of Organic Solar Cells by Reduced Donor‐Acceptor Interface Area. (24th March 2014) - Vandewal, Koen
Abstract The charge carrier lifetime in small molecule: C60 photovoltaic devices is increased by reducing the physical interface area availabe for recombination. For donor contents below 10%, the gain in open‐circuit voltage (Voc) depends logarithmically on the interface area while the energy of the interfacial charge‐transfer state ECT remains invariant.
