NOVELTY - An organic device comprises: at least two electrodes; at least one organic active layer, where the organic active layer is disposed in between two electrodes; and electrode modification layer (120.2). The electrode modification layer is disposed in between two electrodes and in contact with one of the electrodes. The electrode modification layer includes a fluorocarbon compound. The organic device is an organic thin film transistor, organic solar cell or organic photodetector.    USE - As organic device (claimed) e.g. organic electronic devices and organic opto-electronic devices.    ADVANTAGE - The organic device containing electrode modification layer exhibits improved manufacturing capability, and enhanced device performance. The device makes use of a class of fluorocarbon compounds that can effectively form an electrode modification layer in contact with an electrode in organic devices. Also fabrication of the organic device, especially organic light-emitting diode (OLED), is simplified using thermal evaporation method instead of the plasma treatment.
