CdTe thin-film solar cells — •Heinrich Metzner — Institut für Festkörperphysik, FSU Jena, Max-Wien-Platz 1, 07743 Jena

The global industrial production of CdTe solar modules exceeds one Gigawatt per year and so CdTe is probably the most successful thin-film technology of recent years.

In the tutorial, the specific features of the technology are elucidated which make it so competitive. Moreover, the open questions in the materials science of the CdTe-CdS-hetero-structure are discussed and key-issues are identified which are believed to potentially bring the CdTe solar cells to efficiencies well above 20 %.
