Abstract
The invention relates to a glass substrate having enhanced optical properties for optoelectronic devices, wherein said substrate is totally or partially textured, by means of a chemical attack, on at least one of the surfaces thereof with a set of geometric patterns such that the arctangent of the ratio of the mean height of the patterns, Rz, to half the mean distance between the peaks of two contiguous patterns, RSm, is at least equal to an angle of 35° and at most equal to an angle of 80°.
Claims13
A glass substrate, comprising
- a transparent electrode on one face of the substrate,
- wherein the substrate is textured, completely or partially, on a face of the substrate opposite to the face on which the transparent electrode is deposited, by a set of geometric patterns such that an arctangent of a ratio of a mean height of the patterns, Rz, to half the mean distance separating summits of two contiguous patterns, RSm, is at least equal to an angle of 35° and at most equal to an angle of 80°.
