Abstract: A method of forming an organic light-emitting device comprising an anode, a cathode and at least one light-emitting layer between the anode and the cathode, the method comprising the steps of: providing an anode layer supported on a surface of the substrate, wherein the anode layer comprises indium tin oxide formed by sputtering indium-tin oxide onto the substrate surface at a substrate surface temperature of less than 100° C., applying the at least one light-emitting layer and the cathode over the anode layer, and applying a hole injection layer that is located in the organic light-emitting device between the anode layer and the light-emitting layer and in contact with the anode layer. The hole-injection layer comprises a conductive polymer, comprising substituted or unsubstituted thiophene repeat units, and a non-conductive material.

Abstract: The invention relates to a cathode layer stack used for semi-transparent organic photovoltaic devices with improved transmission of light in the visible wavelength range and excellent photovoltaic response. The cathode layer stack comprises an organic buffer layer (14b) deposited over a semi-transparent metal cathode (14c) and a silicon dioxide (SiO2) layer (14a) provided over the organic buffer layer (14b), wherein the refractive index of the silicon dioxide layer is lower than the refractive index of the buffer layer, and wherein the thickness of the silicon dioxide layer is less than 100 nm. In further embodiments, methods of manufacturing the cathode layer stack, organic photovoltaic devices comprising said cathode layer stack and uses thereof are described.
