Abstract
A transparent conductive substrate for solar cells having high haze ratio and little variation of the haze ratio over the entire substrate, and excellent in light transmittance, and the production process of the substrate are provided. A transparent conductive substrate for solar cells comprising a substrate and a TiO2 layer, a SiO2 layer and a SnO2 layer formed on the substrate in this order from the side of the substrate, wherein the thickness of the SnO2 layer is from 0.5 to 0.9 μm and the illuminant C haze ratio is from 20 to 60%.
