PERC Thin Film Solar Cells from Vacuum Coating Systems

Singulus Technologies, provider of production for silicon and thin film solar cells, has signed a framework agreement for the supply of up to 16 vacuum coating systems with M • Cells, a world leading solar cell producers.

The contract between M • Cells and SINGULUS includes the option for the purchase of SINGULAR XP investment at the two-digit million amount. The SINGULAR XP vacuum coating equipment to be used for the rear side passivation of PERC-crystalline solar cells for the production of 500 MW of high-efficiency multi-cell. The delivery of the first aircraft to China is already the first Quarter of 2014 provided.

September 2013 on the Main signed a framework agreement with SINGULUS in Kahl. For Dr.-Ing. Stefan Rinck, CEO SINGULUS TECHNOLOGIES, and the Deputy General Manager of M • Cells, Mr. Zhou Ximing, is a cooperation in the field of solar cell production declared aims.

The vacuum coating machine SINGULAR XP to be used for passivating the rear of the cell in the factory of M • Cells in China. The SINGULAR XP is precisely aligned with the production capacity of a typical cell production line. The system also offers the advantage of SINGULUS that the two systems required for the back surface passivation layer of aluminum oxide (AlOx) and silicon nitride (SiN x) can be applied without breaking the vacuum. Due to its compact design, the system can integrate SINGULAR XP is ideal for upgrading in existing cell production lines.

The fact that the previous cell efficiency at M • Cells can be increased through the use of SINGULAR XP further the competitiveness of M • Cells in the solar industry improved. Thus the demand of the Chinese Government is satisfied, after the future efficiency of multi-crystalline solar cells should be at least 18%.

Dr.-Ing. Stefan Rinck, “The efficiency of solar cells is extremely important. We are convinced that we can combine the latest and most advanced technology from Germany with experience of M • Cells into a joint success “The Deputy General Manager of M • Cells, Mr. Ximing Zhou”. M • Cells has already important achieved success in the area of ??efficiency of multi-cell and I firmly believe that we will make progress very quickly with SINGULUS together so that M • Cells will continue to position itself in the leading role in the international solar market. “

Background PERC

The trend in the solar industry to ever thinner wafers for solar cells at the same time increased efficiencies calls for improved surface passivation of the rear of the cell. SINGULUS TECHNOLOGIES worked in 2012 with the Institute for Solar Energy Research Hameln (ISFH) in the development of cellular technology. In this cooperation, it is possible to increase the efficiency of silicon solar cells by screen printing the usual in the PV industry 17.0% to 18.5% to a record level of 20.1%.
