Latest Patents

One of Daisuke Ando's latest patents is titled "Solar cell and production method therefor." This invention features an interface layer that minimizes interdiffusion between a silicon substrate and copper electrode wiring used in solar cells. It enhances the adhesive properties of copper wiring and achieves improved ohmic contact characteristics. The silicon solar cell comprises a silicon substrate and includes a metal oxide layer formed on the substrate, with wiring made primarily of copper. The metal oxide layer contains specific elements such as titanium or manganese, vanadium, niobium, tantalum, or silicon, and at least one of copper and nickel. Additionally, the layer comprises metal particles that are diffused within it.

Another significant patent is the "Method for firing copper paste." This method aims to improve the sinterability of copper particles to form a copper wiring line with decreased electrical conductivity. The process includes an application step where a copper paste is applied over a substrate, followed by a first heating step in a nitrogen gas atmosphere containing an oxidizing gas. This step oxidizes and sinters the copper particles. A second heating step then reduces the oxidized copper oxide in a nitrogen atmosphere containing a reducing gas.
