GLASS SUBSTRATE, SOLAR CELL, ORGANIC EL ELEMENT, AND MANUFACTURING METHOD OF GLASS SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a glass substrate capable of improving utilization efficiency of light in an optical element such as a solar cell or a light-emitting element, and a manufacturing method of the glass substrate.

SOLUTION: The glass substrate includes a structure with periodical repeating projections and grooves in a length direction on at least one surface, and with a haze rate of wavelengths from 300 nm to 800 nm to be 30% or more. At least on a surface of a glass base material, a structure periodically repeating projections and grooves is formed, then the glass base material is heated to extend into a length direction of the projections and grooves.
