Zusammenfassung

The effenciency of bulk heterojunction photovoltaic devices is limited by the short diffusion length of radiatively created charge carriers, mostly in the range of ca. 20 - 30 nm. Therefore novel design strategies towards efficient bulk heterojunction photovoltaic devices have to be developed. Target of this project is to combine several approaches towards nanostructured components of such device assemblies: 1. Nanostructured metal electrodes can help to increase the collection efficiency of photogenerated charge carriers by reducing the distance to the corresponding electrode. Here, n...
