Janssen, R. (author), Kroon, J.M. (author), Andriessen, R. (author), Aernouts, T. (author), Energieonderzoek Centrum Nederland (author)This article describes how the Solliance Organic PhotoVoltaics (OPV) shared research Program addresses efficiency, lifetime and production costs for (near) future OPV applications. The balance of these three parameters depends of the envisaged application, but at the end, OPV should be able to compete somehow with Si PV in the future. Efficiency...conference paper 2012
