TRANSPARENT CONDUCTIVE SUBSTRATE FOR SOLAR CELL AND SOLAR CELL

摘要

To provide a transparent conductive substrate for a solar cell  whereby the fill factor (FF) and the open circuit voltage can be improved  and a solar cell using it. A transparent conductive substrate for a solar cell  comprising a substrate and at least a tin oxide layer formed thereon  wherein the tin oxide layer has ridges and dents on a surface which is not on the substrate side  an oxide having titanium as the main component is formed on the surface having the ridges and dents  the oxide is particles having an average size of from 1 to 100 nm  and the oxide is contained at a density of from 10 to 100 particles/µm2.
