The invention relates to a glass sheet for producing a thin-film solar module, said sheet being provided with a transparent, electrically conductive metal oxide layer (3) and having a rough surface for scattering the incident light. The side of the glass sheet (2) that faces away from the metal oxide layer (3) is provided with a rough surface for reducing the reflection of light, said surface, together with the metal oxide layer on the opposite side, causing an increase in the diffusely scattered light. The metal oxide layer (3) produces a diffuse fraction of scattering (haze) of between 5 and 40 % at a wavelength of 550 nm for the incident light.
