Manz claims efficiency record for CIGS module
Manz AG, based in Reutlingen, Germany, has claimed a new efficiency world record for CIGS thin-film solar photovoltaic (PV) modules. The figure of 16 percent, certified last week by the testing organisation TÜV Rheinland, closes the gap between CIGS and multi-crystalline PV technology.
Manz's 16 percent efficiency world record is the result of a long-term development partnership with the Stuttgart Centre for Solar Energy and Hydrogen Research of Baden-Wuerttemberg (ZSW).
Following the presentation of 21.7 percent cell efficiency in the laboratory by the research institute for CIGS thin-film technology in the fall of 2014, Manz was able to transfer the essential insights of the technology that was used to mass production.
The increase in performance was achieved mainly using next generation of CIGS semiconductor material, which Manz applies to a glass substrate in a co-evaporation process. Additional technological innovation is a new module design for increasing the active module surface, according to the company. In addition, Manz engineers were able to reduce optical losses.
Dieter Manz, founder and CEO of Manz AG said: "Building on the know-how of ZSW and our own experts, it is thus absolutely realistic that we will already be able to present module efficiencies of significantly higher than 17 percent in the near future, produced on our innovative production line in Schwäbisch Hall. We have already mastered the necessary processes in the lab, such as the after-treatment of CIGS coatings. The goal of our joint efforts is the further reduction of electricity costs - around the world, under all climatic conditions."
