Singulus Presents New Modular System for Chemical Buffer Layer Deposition
Singulus technologies, a global supplier of Chemical Buffer Layer Deposition for CIS/CIGS thin-film solar cells, will present the latest development in this technology at the coming SNEC 2015 in China. With the development of a completely new concept for the TENUIS II CBD system Singulus will open up the way to cost-effective production. This machine is a central component for the manufacturing of CIS/CIGS thin-film solar cells.
The industrial manufacturing machines of the TENUIS type have a modular cluster system and enable both significant savings in terms of required floor space and the simultaneous one-sided coating of two substrates. The new generation of the TENUIS plant offers substantial cost advantages in the production of high performance CIS/CIGS thin-film solar cells. With application and temperature control, the process time has been reduced, bringing the positive effect of significantly higher production line output.
The new system makes it possible to use alternative buffer layer by replacing the intermediate layer system consisting of cadmium sulfide and zinc oxide by a combination of zinc oxide sulfide and zinc magnesium.
The new generation of the TENUIS plant offers substantial cost advantages in the production of high performance CIS/CIGS thin-film solar cells. Furthermore, the costs are significantly reduced by process adjusted temperatures and by the very efficient use of process chemicals enabling the new plant to consistently exploit the savings potential in the manufacturing of thin-film solar cells. Singulus offers wet processing systems from R & D, through over pilot use to full production range 60, 150 and 300 MW.
Through its production systems, Singulus supplies wet-chemical processing and selenization systems for second-generation CIGS/CIS cells and has thus positioned itself at the vanguard of technology leaders for pioneering development and production systems. Inline sputtering systems add a further production stage to the portfolio, which already spans the key processes of CIGS/CIS cell production. In light of the anticipated volume of investment in production lines for CIGS/CIS thin-film solar cells.
