Calyxo With New All-time High In Production For Its Thin-film Modules


TS Solar Calyxo GmbH has again significantly
increased the efficiency of its thin-film solar modules. The European market
leader from Bitterfeld-Wolfen improved the output of its modules by around 20
percent from an average of 90 watts to 111 watts per module. The efficiency of
the modules reads now 15.4 percent instead of 13 percent previously. Production
has already started.

Together with its parent company TS Group, Calyxo
brought the new generation of modules to market maturity in just six months of
development. The performance of the new modules has been independently
confirmed by Coburg Univercity of Applied Sciences and Arts. Calyxo is the
world's number two manufacturer of cadmium telluride (CdTe) thin-film solar

"This further increase brings us for the first
time within range of the efficiency of polycrystalline modules, which have so
far been ahead in terms of performance," emphasized Dr. Stephan Koehne,
CEO of the TS Group. Compared to thin-film solar modules, polycrystalline
modules have the disadvantage that they are less robust and less performant in
low light conditions. Köhne continued: "Our next goal is to close the gap
to monocrystalline cells in the near future. These are currently even more
efficient, but much more expensive." With the help of patented process
improvements and further investments, Calyxo intends to achieve an efficiency
of 18 percent in the near future to become the market leader.

Calyxo is among the few glass-glass module
manufacturers in the market and based on this their modules are extremely
robust and long-term stable. The conventional crystalline modules usually have
a plastic film on the back instead of glass, which can make these modules less
reliable, especially in climates with hot temperatures and high humidity. In
addition to their longer service life, thin-film solar cells also cope better
with shading and achieve higher yields in poor lighting conditions. In
addition, the efficiency is less sensitive to high temperatures. In electricity
generation, this can lead to an overall advantage of up to 20 percent per year
compared to comparable crystalline solar modules.

"The efficiency improvement of crystalline solar
modules is somewhat levelling out in the near future," adds Dr.-Ing.
Michael Bauer, Managing Director of TS Solar Calyxo GmbH. "The potential
of thin-film solar cells, on the other hand, is enormously high. In research,
it is assumed that the relatively new thin-film technology can achieve
efficiencies of up to 30 percent.” Bauer added further "In TS Group, we
have found a technology
company that knows and understands the market. I am
convinced that together we will be able to further increase the overall
performance of the modules.”
