SILICON THIN FILM SOLAR CELL HAVING IMPROVED UNDERLAYER COATING

摘要

A spcon thin film solar cell includes a substrate and an undercoating formed ovef at least a portion of the substrate. The undercoating includes first layer haAg tin oxide or titania and a second layer having a mixture of oxides of at lea& two of Sn, P, Si, Ti, A1 and Zr. A conductive coating is formed over at least a p b o n of the frst coating, wherein the conductive coating includes oxides of 9 one& more of Zn, Fe, Mn, Al, Ce, Sn, Sb, Hf, Zr, Ni, Zn, Bi, Ti, Co, Cr, Si - or In or 6 alloy of two or more of these materials.
