Since the end of 2008, Soltecture has begun work on second generation technology, which deploys a CIS layer based on selenium instead of sulphur (indicated by the abbreviation CIGSe instead of CIGS). In the laboratory this technology has been proven to yield the highest efficiencies in the thin- film space.


CIGS- and CIGSe modules are produced with the same equipment in Soltecture’s 35MW production plant in Berlin, Germany. Only for the CIGSe coating process, new specially developed equipment is being used. Yearly production capacity for the product line CIGS is 20MW; the capacity for CIGSe is currently being expanded from 5MW to 15MW.


Soltecture’s research and development work as well as its highly flexible production line in Berlin provides the ideal framework for the development and production of the thin-film products of the future.


In ten years Soltecture has evolved from a leading manufacturer of high-performance thin-film modules to a provider of integrated system solutions. Soltecure offers standardised solutions for intelligent integration of their high-performance and optically aesthetic thin-film modules for construction challenges such as roofs, factories, and modern facades.


“With their engineering expertise and years of experience in solar technology our engineers constantly develop new PV solutions that are perfectly adjusted for solar architecture,“ explains Henrik Kruepper, Executive Director and Chief Sales Officer at Soltecture. “We offer our clients solar integration from one source and that makes us successful in the market.“


These developments have been made possible by the trust of international investors. In recent years, renowned international investors including Intel Capital, Climate Change Capital, and the Vattenfall Europe- and GdF Suez-supported BEU Fund have provided Soltecture with growth financing amounting to more than €110 million.


In the newest financing round on January 2011 investors led by Intel Capital provided €18.8 million for the further development of the company’s innovative CIGSe techology. With this fresh capital,


Soltecture is forging ahead with development of production machinery and increasing the capacity of its fully-automated manufacturing facility for the new CIGSe modules.

PKU makes China’s first CIGS solar integrated power circuit


In the 6th Asia Solar Photovoltaic Industry Exhibition, the first copper indium gallium selenide (CIGS) solar integrated power circuit of China was exhibited in Shanghai on May 5.


Technically supported by Peking University (PKU), Henan Yanyuan Photovoltaic Technology Co., Ltd developed the China’s first CIGS solar integrated power circuit. This new product proves to be a new innovation in Chinese Solar Photonics Industry. With the booming solar industry nowadays, people are familiar with solar collectors and solar cells. However, what they don’t quite know is the combination of these two elements–the solar integrated power circuit, a new type of CIGS solar cell’s application. It provides a new approach to promote its scale production.


Gan Zizhao, professor of the PKU School of Physics and member of the Chinese Academy of Sciences (CAS), talked about the invention during an interview. “The application of CIGS solar cell is going to be the development trend in the solar industry. It reduces pollution and costs compared with the old material, which is mainly silicon. Moreover, it’s cheaper and more efficient,” said Professor Gan.


The PKU research team had independent intellectual property of this technology, added Professor Gan. Compared with other few ountries like US and Germany, they are still in an intermediate level, having a long way to reduce the gap in craftsmanship. However, there are large potential markets for this innovation in China.
