Manufacturing of More Efficient Crystalline Solar Cells Namely PERC Solar Cells

PERC Solar Cells

PERC Solar Cells ( Solar Thermal Magazine) Kahl am Main, May, 2013

Against the background of a still weak market and political discussions SINGULUS TECHNOLOGIES (SINGULUS) reports interesting projects talks at the solar trade Fair SNEC in Shanghai. In particular, solutions for the manufacturing of more efficient crystalline solar cells, the so-called PERC cells, were in the spotlight.

For the upgrade of existing cell production lines only three additional production steps are required. Before coating the cell rear side it is smoothed with a wet-chemical glaze in a LINEA II machine. The complete dielectric passivation layer is emitted in the SINGULAR XP vacuum coating machine.

For the rear side contacts through a laser process, SINGULUS is closely cooperating with a partner. With the integration of these additional production steps into existing manufacturing lines cells can be produced with about 1 % improved efficiency.

For the manufacturing of CIGS solar modules SINGULUS offers custom-made solution for the various processing steps. Many talks have shown that the producers of modules attempt to implement their own process solutions into their industrial manufacturing. SINGULUS is in intensive talks for both R & D machines as well as for large production equipment in the CIGS area.singulus solar

China continues to expand the CIGS technology extensively and also published this in its 12th five-year plan, which has been in place since 2011.

Dr.-Ing. Stefan Rinck, Chief Executive Officer of the SINGULUS TECHNOLOGIES AG, comments: “Our production solutions help cell manufacturers to save money with a simultaneous increase in cell efficiency. In particular, our production equipment for all the important steps of the CIGS module producers provides our partners the flexibility to optimally implement their own process solutions.”

Profile SINGULUS TECHNOLOGIES:

SINGULUS TECHNOLOGIES develops innovative technologies for efficient production processes, which only make use of resources conservatively. New production technology combined with sustainable processes and the use of novel materials can decouple the use of resources from economic growth in the long-term. SINGULUS TECHNOLOGIES’ innovative power and competitiveness are strengthened by these new technologic developments.

With its Optical Disc segment SINGULUS TECHNOLOGIES is the market leader for CD, DVD and Blu-ray Disc production equipment. As the only engineering company worldwide SINGULUS TECHNOLOGIES today already provides the machine technology for three-layer Blu-ray Discs with a storage volume of about 100 GB.

In the Solar division SINGULUS TECHNOLOGIES is a recognized supplier for new machines concepts and production processes for crystalline and thin-film solar cells, which increase the efficiency of solar cells and reduce their production costs. SINGULUS TECHNOLOGIES establishes itself as a development partner and machine supplier for technologies enabling a sustainable energy provision on the basis of renewable energies.

In the Semiconductor segment SINGULUS TECHNOLOGIES focuses its activities on the vacuum coating of wafers with ultra thin layers for the production of MRAM memory, thin-film write/read heads and other semiconductor applications.

 

SINGULUS TECHNOLOGIES continues to expand its know-how in vacuum coating, the automation and process technology as well as the integration of manufacturing lines in order to develop new work areas. To strengthen the existing business activities SINGULUS TECHNOLOGIES is currently reviewing concrete acquisition opportunities.

 

New application areas for vacuum deposition technology are the focus of the further development.
