Abstract
A substrate for a solar cell is provided which comprises a support having a metal surface and a zinc oxide film formed on the metal surface and having a water content of 7.5×10−3 mol/cm3 or less, preferably 4.0×10−4 mol/cm3 or more. Thereby, the increase of series resistance and the generation of shunt are prevented and the efficiency such as Jsc and the chemical stability are improved, thus obtaining a solar cell with a zinc oxide film having optimal overall characteristics.
