Latest Patents

Moreno's latest patents include a method of texturing the surface of a silicon substrate and a textured silicon substrate for a solar cell. This invention focuses on a method for texturing the surface of a gaseous phase silicon substrate. The process involves exposing the surface to an SF/O radiofrequency plasma for a duration of 2 to 30 minutes. This exposure produces a silicon substrate with a textured surface featuring pyramidal structures. The method ensures that the power density generated using the radiofrequency plasma is greater than or equal to 2500 mW/cm, while maintaining a pressure in the reaction chamber of less than or equal to 100 mTorrs. This results in a silicon substrate with inverted pyramidal structures, enhancing its performance in solar applications.

Another notable patent involves a method for producing a multilayer film that includes at least one ultrathin layer of crystalline silicon. This method begins with a substrate that has a crystalline structure and a cleaned surface. The process includes exposing the cleaned surface to a radiofrequency plasma generated from a gaseous mixture of SiF4, hydrogen, and argon. This exposure forms an ultrathin layer of crystalline silicon with an interface sublayer containing microcavities. The method further involves depositing at least one layer of material on this ultrathin layer, followed by annealing the substrate at temperatures exceeding 400°C to facilitate the separation of the multilayer film from the substrate.
