Q-Cells crystalline 60-cells modules set two new world records

  • Efficiency world record of 18.5 per cent for a multi-crystalline module exceeds own record of 18.1 per cent
  • Record-setting module output of 283 watts based on 60 quasi-monocrystalline solar cells
  • Innovative Q.ANTUM cell concept offers highest performance classes on the basis of optimised standard technology

Bitterfeld-Wolfen (Germany), 17 January 2012 – Q-Cells SE, one of the world’s leading photovoltaic companies, has set two new world records for multi-crystalline solar modules. The independent calibration laboratory of the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg confirmed the module efficiency of 18.5 per cent in reference to the aperture area for a module with 60 multicrystalline solar cells. With this efficiency record, Q-Cells has broken its own world record of 18.1 percent set in the summer of 2011. Additionally, the independent calibration laboratory of the Fraunhofer ISE confirmed a peak output of 283 watts for a quasi-monocrystalline module. Q-Cells therefore has the currently most powerful module among competitively priced quasi-monocrystalline modules. Q-Cells also holds the current world-record in the field of mono-silicon modules since September 2011, with a performance class reaching 287 watts.

“With these world records, Q-Cells is once again underscoring its technology leading position in terms of efficiency as well as the output of its products,” says Peter Wawer, Head of Technology at Q-Cells SE. “Thanks to our close cooperation between research, development and production at the Thalheim location, we are able to bring innovative technologies into serial production quickly. This allows us to offer top quality products with sustainable yields to our clients."

Both records are based on the innovative Q.ANTUM cell concept of Q-Cells. The market introduction of the Q.ANTUM solar cells and modules is planned for 2012. Pilot production of the new cell concept is now underway in Thalheim. In April 2011, the Q.ANTUM solar cell by Q-Cells already set the world record for large-scale multicrystalline solar cells with an efficiency of 19.5 per cent. Multicrystalline or quasi-monocrystalline silicon wafers with a thickness of 180 µm, mirrored and passivated with functional nano-layers on the rear side, are the base material for the solar cells that were used. The innovative structure of the rear side, made of dielectric layers in combination with local contacts, improves the optical and electrical characteristics of the solar cell and results in a significant performance increase compared to the standard BSF (back surface field) technology which is currently in widespread use. This innovative structure of the reverse side is compatible with various grades of silicon and very thin wafers. With the latest high-efficiency technologies developed for Q.ANTUM and their optimisation for cost-effective wafer materials, Q-Cells is establishing the prerequisites for the efficient production of crystalline modules in the high-performance segment.

Q-Cells is currently marketing its second generation of solar cells and solar modules worldwide. The company offers a unique quality guarantee for all new products introduced to the market. Two seals document outstanding performance and long-term stability: the “Q-Cells Yield Guarantee” and “VDE Quality Tested“. The Q-Cells Yield Guarantee encompasses technology innovations for quality control and to guarantee yields; it is based on better performance and higher yields. VDE Quality Tested documents the improved long-term stability of the modules in order to ensure that investing in Q-Cells solar products also pays off in the future.
