Calyxo GmbH Reached 16.2% Cell Efficiency

Calyxo GmbH Bitterfeld / Wolfen - Thalheim reached 16.2% cell efficiency on its low cost cadmium-telluride (CdTe) technology. The testing body SGS Germany has officially confirmed the record numbers.

Bitterfeld-Wolfen, Sachsen-Anhalt Calyxo GmbH confirms the tremendous performance potential of photovoltaic( ) devices based on CdTe technology made by its proprietary low cost atmospheric deposition technology.

"This result shows the efficiency potential of Calyxo's hot and fast deposition technology. Based on this achievement we are confident to reach 17%-18% cell efficiency and 14-15% top module efficiency later this year", said Michael Bauer, Calyxo's Chief Technology Officer.

Calyxo GmbH currently operates a 25 MWp production line with over 150 employees at the manufacturing plant that has been in commercial production since 2009 in Bitterfeld / Wolfen-Thalheim, also known as Solar( ) Valley in Saxony-Anhalt. Calyxo GmbH is totally owned by the original technology provider Solar Fields, LLC, Toledo, Ohio, U.S.A.

The company:

Calyxo GmbH - Independent since 2011 and on the road to expansion!

Calyxo GmbH, founded in 2005, produces thin-film solar modules based on cadmium telluride (CdTe) technology. After the company split from Q-Cells in February of 2011, the former technology provider Solar Fields took over Calyxo GmbH and invested in a second production line with a capacity of approx. 60 MWp, which will commence production in 2012. Calyxo GmbH currently manufactures a module volume representing an annual power generation capacity of 25 MWp at their production facilities Bitterfeld/Wolfen-Thalheim, in the so-called "Solar Valley" in Saxony-Anhalt, Germany. All Calyxo modules are thus "Made and Developed in Germany".

Research and rapid further development of the Calyxo CdTe is constantly being driven ahead, in collaboration with the American parent company Calyxo USA Inc. The CdTe technology has an enormous potential to reduce the costs of solar power generation. Thin-film solar cells are economic to manufacture and can convert solar energy to electricity under the most unfavourable weather conditions. The modules still operate efficiently on roofs that are not directly aligned to the south.

The production process used for Calyxo CdTe thin-film modules also helps to reduce environmental contamination. The cadmium used for the CdTe( ) modules is a waste product from the mining industry that must otherwise be expensively stored to prevent environmental damage. The CdTe technology refines the cadmium and tellurium to a water-insoluble semiconductor to form the basis of the Calyxo thin-film module. The cadmium telluride is then safely bonded between two glass plates to provide a reliable source of solar power for decades. The CdTe modules also offer an unmatched energy payback time of about 1.5 years. The energy payback time is the time required for a product to generate the same amount of energy that was used for its manufacture.
