We demonstrate that stacking of solution-processed organic and metal oxide interfacial layers gives highly charged selective low ohmic cathodes. The incorporation of a polyoxyethylene tridecyl ether interfacial layer between ITO and solution-processed titanium oxide (TiOx) raised the power conversion efficiency of inverted organic photovoltaics to 3.6%, an improvement of around 15% in their performance over comparable devices without the organic interfacial layer.||ISSN:||1077-3118||DOI:||10.1063/1.2885724||Rights:||© American Institute of Physics||Type:||Article||Affiliation:||Konarka Technologies||Affiliation :||Konarka Technologies GmbH
