Organic Solar Cells were fabricated by co-evaporation of C 60 :Cu-Phthalocyanine blend films in vacuum on poly(ethylene dioxythiophene):polystyrene sulfonic acid (PEDOT:PSS) coated indium–tin oxide substrates. At 80 nm blend film thickness external quantum efficiencies of up to 58% were recorded. Two different methods were applied to manipulate the morphology of the active film: Current treatment...
The surface of transparent indium-tin oxide (ITO) electrode is electronically modified by a chemically bonded monolayer of organic molecules or a single layer of adsorbed acid ions. The electrode surface was examined with Kelvin probe force microscopy in vacuum. Treatments with phosphoric acid and periodic acid both lead to an increase in work function of about 0.7 eV with a good homogeneity. For...
