Abstract: This invention relates to a memory cell which comprises a capacitor having a first electrode and a second electrode separated by a dielectric layer. Such dielectric layer comprises a layer of a semi-insulating material which is fully enveloped by an insulating material and in which an electric charge is permanently present or trapped therein. Such electric charge accumulated close to the first or to the second electrode, depending on the electric field between the electrodes, thereby defining different logic levels.

Abstract: A thin film amorphous silicon solar cell may have front contact between a hydrogenated amorphous silicon layer and a transparent conductive oxide layer. The cell may include a layer of a refractory metal, chosen among the group composed of molybdenum, tungsten, tantalum and titanium, of thickness adapted to ensure a light transmittance of at least 80%, interposed therebetween, before growing by PECVD a hydrogenated amorphous silicon p-i-n light absorption layer over it. A refractory metal layer of just about 1 nm thickness may effectively shield the oxide from the reactive plasma, thereby preventing a diffused defect when forming the p.i.n. layer that would favor recombination of light-generated charge carriers.

Abstract: Solar thin film modules are provided with reduced lateral dimensions of isolation trenches and contact trenches, which provide for a series connection of the individual solar cells. To this end lithography and etch techniques are applied to pattern the individual material layers, thereby reducing parasitic shunt leakages compared to conventional laser scribing techniques. In particular, there may be series connected solar cells formed on a flexible substrate material that are highly efficient in indoor applications.
