Latest Patents

Chern holds a patent for an "Induced Junction Solar Cell and Method of Fabrication." This invention involves fabricating an induced junction solar cell on a p-type silicon substrate. The process begins with diffusing a grid of criss-crossed current collecting n.sup.+ stripes and thermally growing a thin SiO.sub.2 film. Subsequently, silicon-rich chemical vapor deposition (CVD) is used to produce a layer of SiO.sub.2 with inherent defects that act as deep traps for spontaneous positive charges. Ion implantation is then employed to enhance the stable positive charge distribution, creating a greater inversion layer in the p-type silicon near the surface. The final steps include etching through the oxide to create parallel collecting stripes and producing a metal pattern that consists of contact stripes and a diamond-shaped current collection bus. The reverse side of the cell is then metallized.
