Latest Patents

Seung P Li holds a patent for an "Induced Junction Solar Cell and Method of Fabrication." This invention involves the fabrication of an induced junction solar cell on a p-type silicon substrate. The process begins with the diffusion of a grid of criss-crossed current collecting n.sup.+ stripes, followed by the thermal growth of a thin SiO.sub.2 film. Using silicon-rich chemical vapor deposition (CVD), a layer of SiO.sub.2 with inherent defects is produced, which serves as deep traps for spontaneous positive charges. Ion implantation enhances the stable positive charge distribution, creating a greater inversion layer in the p-type silicon near the surface. After etching through the oxide to parallel collecting stripes, a metal pattern is created, consisting of contact stripes over the exposed collecting stripes and a diamond-shaped pattern that functions as a current collection bus. The reverse side of the cell is then metallized. This innovative approach has the potential to improve the efficiency of solar cells.
