The present invention is directed to process for preparing a device comprising a first layer and a first electrode, the method comprising forming the first layer over a first electrode by applying a liquid anhydrous composition comprising at least one metal oxo alkoxide and at least one solvent, onto a surface, the surface being selected from the surface of the first electrode or the surface of a layer being located over the first electrode, optionally drying the composition, and converting the composition to a metal oxide-containing first layer, and forming a second electrode over the first device layer, wherein the method further includes forming a layer comprising quantum dots over the first electrode before or after the formation of the first layer and to the device itself. |
