|Issue Date:||2008||Publisher:||American Institute of Physics||Source:||Solar Energy Materials and Solar Cells. Volume 93, Issue 11, pp. 1963-1967||Abstract:||We present highly efficient inverted polymer:fullerene bulk-heterojunction solar cells by incorporation of a nanoscale organic interfacial layer between the indium tin oxide (ITO) and the metal oxide electron-conducting layer. 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.||URI:||http://ktisis.cut.ac.cy/handle/10488/1269||DOI:||10.1063/1.2885724||Rights:||©2008 American Institute of Physics||metadata.dc.type:||Article|
