Abstract
Abstract A method for producing a carrier material for use in a solar generator composed of a plurality of solar cells electrically conductively connected together and fastened to the carrier material. The method includes providing a glass fiber fabric composed of intersecting glass fibers; applying liquid plastic composed of a plastic dissolved in a solvent to the points of intersection of the glass fibers; evaporating the solvent; and hardening the plastic so that the glass fibers are firmly mechanically connected together by the hardened plastic at the points of intersection.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
98 words
A method for producing a carrier material for use in a solar generator composed of a plurality of solar cells electrically conductively connected together, the solar cells being fastened only on one side thereof to the carrier material, said method comprising: providing a glass fiber fabric composed of intersecting glass fibers; applying liquid plastic composed of a plastic dissolved in a solvent to only the points of intersection of the glass fibers; evaporating the solvent; and hardening the plastic so that the glass fibers are firmly mechanically connected together by the hardened plastic at the points of intersection.
