It solar cells with high quantum efficiencies are claimed based on rare-earth compounds as electron emitter 2 eV for electron work function below, an adjacent tunnel layer, and an n-doped semiconductor collector layer with the minimum vacuum level and the same height from Inflatable [...] . This high efficiencies are possible in the direct conversion of light into electrical energy. The energy of the photons electrons from the emitter drop-in end photons solve minus the work function of the emitter from. "Hot" electrons are injected into a thin This, insulating tunnel layer. You cross the tunnel layer ballistically [...] and shall take on negative onto a collector. The tunnel layer consists of rare earth oxides or with a layer thickness of 0.2 to 10 nanometers [...] . The collector layer is made from a plasma deposited in a preferred embodiment, from a 1, 000 nanometers thickness n-doped diamond layer of less than. After passage through the tunnel layer without substantial energy loss on the vacuum level of the collector surface in the electrons enter the [...] of the collector a. In inorganic or organic light emitting diodes can also material combinations The, guns, low-light enhancers , are used as cold cathodes [...] or generally without vacuum gap.
