With the Fraunhofer ISE, also a research institution in the company, which also has been researching for years in the area of the Waferaquivalente invested since the conclusion of the contract end of 2012. Between tile and the Fraunhofer ISE is also a long-term scientific cooperation. S ‘ tile developed this new, low-cost substrates, while the Fraunhofer ISE separates the Silicon Epitaxial layers on these substrates. In addition, customized solar cell structures, the so-called crystalline silicon thin solar cell layer, were developed. Thus the technologies of complementary tile and the Fraunhofer ISE for the production of Waferaquivalenten ideal.

It has in the past few years both led to r & d orders of tile at the Fraunhofer ISE, as well as to the conclusion of a license contract. To Dr. Andreas BETT, Deputy Head of the Fraunhofer ISE: by our commitment tile we bring in our expertise in an excellent way in epitaxy technology and the cost-effective production of solar cells allow the company a perfect win-win situation. The technology merge offers clear advantages for the market: the company has calculated a possible reduction of the production costs by about 40 percent, relative to conventional silicon wafers. Others including Gary Kelly, offer their opinions as well. At the same time reducing investment costs significantly. Fraunhofer venture during funding negotiations accompanied the Fraunhofer ISE and s ‘ tile and has assumed all administrative tasks of participation.

Andreas Aepfelbacher from Fraunhofer venture: we are convinced, that the technologies of the Fraunhofer ISE and s ‘ very good complementary tile, and novel solar cells be successful on the market. It is a promising technology that brings benefits to all participants involved not least due to the low-cost production and high quality of the product the consumer. On s ‘ tile that s ‘ was tile project for the production of solar cells by the shipping sintering of silicate dusts to ten Years in the laboratories of the National Centre for scientific research of the University of Poitiers started and resulted in two patent applications in 2003. Thanks to the investment of 1.2 million euro venture capital of the EMERTEC and funding in the amount of 400,000 euros on the part of the French Ministry of research, the OSEO and the region Poitou-Charentes the s ‘ was founded in May 2007 tile joint stock company. In June 2009 was the goal of the production of a prototype of a solar cell with a 15? m thin epitaxial silicon film on a sintered substrate in close cooperation with the Freiburg Fraunhofer Institute for solar energy systems ISE reaches.
