Method for producing a photoelectric converter comprising a transparent conductive substrate

摘要

The present invention provides a transparent conductive substrate having optical transparency and conductivity that have been improved in a well-balanced manner. The transparent conductive substrate of the present invention includes a transparent base and a conductive metal oxide film formed on the base. This metal oxide film contains tin and fluorine. In a profile of the metal oxide film determined in the depth direction by SIMS, the value obtained by subtracting the minimum Imin of the ratio of sensitivity of the fluorine to that of the tin from the maximum Imax thereof is at least 0.15. The maximum Imax is higher than 1 while the minimum Imin is lower than 1. Furthermore, the position where the maximum Imax is obtained is closer to the surface of the metal oxide film as compared to the position where the minimum Imin is obtained.
