Latest Patents

Tetsuya Satou's latest patents focus on methods for producing photovoltaic cells. The first patent describes a method that involves applying a first p-type diffusion layer forming composition on a semiconductor substrate. This composition includes a p-type impurity-containing glass powder and a dispersion medium. It also details the application of a second p-type diffusion layer forming composition with a lower concentration of p-type impurity. The process includes heat-treating the substrate to form a p-type diffusion layer and subsequently forming an electrode on the partial region.

The second patent outlines a similar method for producing photovoltaic cells, but it focuses on n-type diffusion layers. This method includes applying a first n-type diffusion layer forming composition, which also contains an n-type impurity-containing glass powder and a dispersion medium. The second n-type diffusion layer forming composition is applied to a different region of the substrate, with a lower concentration of n-type impurity. The heat treatment process is again employed to form an n-type diffusion layer, followed by the formation of an electrode.
