Latest Patents

One of his latest patents is titled "Sulfurization and selenization of electrodeposited CIGS films by thermal annealing." This invention relates to a method for producing thin layers of semiconductor alloys of the I-III-VI type, which includes sulfur for photovoltaic applications. The process involves depositing a heterostructure on a substrate, which includes a thin layer of precursor I-III-VI that is primarily amorphous, along with a thin layer containing sulfur. The heterostructure is then annealed to facilitate the diffusion of sulfur into the precursor layer, promoting partial crystallization of the I-III-VI alloy with sulfur stoichiometry. Additionally, a layer of selenium may be deposited to assist in the recrystallization processes.

Another notable patent is the "Method of producing thin films of compound I-III-VI, promoting the incorporation of III elements in the film." This invention describes a method for producing thin films of compound CIGS through electrodeposition. The process involves adding a surface-active compound, such as dodecyl sodium sulfate, to the electrolysis bath solution to enhance the incorporation of gallium into the CIGS films.
