<p>A substrate-independent manufacturing method for a solar cell with chalcopyrite absorber layer (4, 5) is proposed wherein a desired alkali content is obtained in the finished absorber layer by dosed addition of Na, K, or Li during the manufacturing process. An additional drive-in of alkali ions from a potentially alkali-containing substrate (1) is prevented by providing a diffusion barrier layer (2) between substrate and absorber layer.</p> |
