PRESS RELEASE
Q-Cells SE develops world record-setting solar cell with 19.5% efficiency
rating
- Polycrystalline 6-inch solar cell achieves an efficiency rating of
19.5%
- Independent Fraunhofer ISE institute confirmed world record
- Solar cell based on new Q.ANTUM cell concept has been nominated for the
Intersolar Award 2011
Bitterfeld-Wolfen (GER), 1 June 2011 - Q-Cells SE, one of the world's
leading photovoltaics companies, has marked a new world record in the field
of major polycrystalline solar cells. The independent calibration
laboratory of Fraunhofer ISE (Institute for Solar Energy Systems) in
Freiburg (Germany) confirmed the record efficiency rating of 19.5% on an
area of 243 cm². The high-performance solar cell is based on the new
Q.ANTUM cell concept, developed by Q-Cells in recent years. On the occasion
of the biggest industry fair in the world, Intersolar 2011 in Munich,
Q-Cells has been nominated for the Intersolar Award 2011 for a first kind
of these solar cells, achieving an efficiency rating of 18.45%.
'The new world record is proofing Q-Cells' leading position in the
crystalline solar cells market. We have already managed to significantly
improve the cell efficiency rating thanks to our new cell concept Q.ANTUM,
and we will further optimise this technology to achieve efficiencies of
more than 20%,' said Peter Waver, Senior Vice President Technology with
Q-Cells SE, explaining the importance of this development. 'We are proud to
have been nominated for the Intersolar Award 2011. This shows that our
development will be a determining factor for the entire photovoltaics
industry.'
In Q-Cells' in-house research centre at the Thalheim site (Germany), a
polycrystalline, 180-µm-thick silicon wafer was metallised and passivated
with functional nanolayers on the back side. This new type of structure for
the back side, consisting of dielectric layers combined with local
contacts, improves the solar cell's optical and electrical characteristics
and significantly boosts output as compared to the previous standard
technology, which uses a completely aluminum-metallised rear.
At the beginning of the year, Q-Cells already broke a world record in the
field of polycrystalline solar modules, drawing on this cell design and a
cell efficiency rating of 18.45%. The European Solar Test Installation
(ESTI) confirmed a total module output of 268 watts and the module
efficiency rating of 17.84% on the aperture area.
Q-Cells consistently optimised the individual steps of cell production and
managed to improve the top efficiency rating from 18.45% by more than 1% to
19.5%. The innovative cell structure is suitable for a range of silicon
qualities and for very thin wafers. This opens up potential for further
cost savings in the industrial production of solar cells. Since research,
development and production are closely integrated at the German Thalheim
site, Q-Cells will now use the research results for series production of
the third generation of Q-Cells solar cells and modules.
The state of Sachsony-Anhalt and the German federal government, among
others, provided funds for the development activities. Some activities were
carried out in the framework of the top cluster Solarvalley Central
Germany.
