The thin-film solar cell includes at least one Na2O-containing multicomponent substrate glass, which is not phase demixed and has a content ofβ-OH of from 25 to 89 mmol/l. The process for making a thin-film solar cell includes the following steps: a) providing an Na2O-containing multicomponent substrate glass, which has a content ofβ-OH of from 25 to 80 mmol/l and is not phase demixed; b) applying a metal layer to the substrate glass, which forms an electrical back contact of the thin-film solar cell; c) applying an intrinsically p-conducting polycrystalline layer of a compound semiconductor material, in particular a CIGS compound semiconductor material, which includes at least one high-temperature step at a temperature of >550° C.; and d) applying a p/n junction.
