Kristallzüchtung, Humboldt- und Technische Universität, as well as the Helmholtz Zentrum, which are active in this field, but also companies like the u2t Photonics AG, a spin-off from Fraunhofer HHI. “When making a phone-call in the US, your chances of the optical components involved having been made in Berlin are pretty good,” said Norbert Grote.


CIS firm Sulfurcell is reborn as Soltecture


The new name ‘Soltecture’ is intended to get to the heart of the firm’s core competencies and stands for superior performance in solar, technology, and architecture.


On the ten-year anniversary of its founding, CIS thin-film pioneer Sulfurcell will be renamed Soltecture.


The Berlin-based company’s new name is intended to reflect the excellence of the company’s integrated solar solutions.


PV system solutions.”


Soltecture (Sulfurcell) can look back on a ten-year history of success in CIS thin-film technology. Soltecture has been a pioneer in the PV thin- film space since its founding and continues its technological leadership today. From the early module market introduction of thin-film modules based on CIS semiconductors in 2005 and the ramp-up of three fabrication lines to recent record efficiencies of 13.0 % with innovative CIGSe technology, Soltecture stands for excellence in thin- film.


Soltecture has received multiple awards for its cutting-edge research and product development. In 2010 Eurosolar awarded the company the badge of the German Solarprize and the Germany-wide initiative “Land of Ideas” recognised Soltecture (Sulfurcell) as an exemplary and sustainable company. Furthermore, the UK’s Guardian newspaper listed Soltecture among the “hottest 100 clean technology companies in Europe” in the years 2009 and 2010.


Soltecture claims to achieve worldwide peak results with CIS solar modules based on CIGSe semiconductors. The company unveiled the new high-efficiency modules to the public at the end of 2010. TÜV Rheinland officially confirmed the output of 94 W or 12.6 % aperture efficiency. Only weeks later 13.0 % has already been achieved and industrial mass production of the new products has begun. During continuing shift operation (24/7) within just three months of the start of production, a yield of over 80% has been achieved. More than 4 out of 5 high efficiency solar modules produced are meeting the required specifications.


New company name Soltecture on headquarters in Berlin, Germany


CEO and Founder Nikolaus Meyer explains:


“The renaming is a logical step that takes the evolution of our company into account. The new name ‘Soltecture’ gets to the heart of our core competencies and stands for superior performance in solar, technology, and architecture. With the renaming we are signalling and underlining the development of the company from module manufacturer to a provider of optimum integrated

The rapid increase in yields in Soltecture’s state- of-the-art mass production and the marginal deviance in module power (90W +/- 3W) confirm process stability, which is widely recognised as an extraordinary challenge in thin-film module production.


In the coming 10-16 months, Soltecture aims to increase module-efficiency to more than 14% and production yields to over 90%. Based on successful quality control and on the background of series production readiness, the sales and distribution of the new modules have already begun.
