TENUIS II

Modular System for Chemical Buffer Layer Deposition CIGS & CdTe Thin-Film Solar Cells

SINGULUS TECHNOLOGIES is the market leader for chemical buffer layer deposition for CIS/CIGS thin- film solar cells. With the development of a completely new concept for the TENUIS II system, SINGULUS TECHNOLOGIES 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 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 TENUIS II also provides advantages upon commissioning and in the ramp-up stage. Because of the new cluster design, the commissioning can commence modularly after a short installation time and the first substrates can be coated. The following cluster can be assembled simultaneously or consecutively. Correspondingly, the TENUIS II meets the ever increasing demands of the market with respect to the reduction of the commissioning and ramp-up times.

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.

Due to new and unique concepts in terms of dosing and temperature control, the developers at SINGULUS were successful in reducing the process time by up to 30 %, resulting in a considerably higher output in production. Furthermore, the costs are significantly reduced by temperature profiles adjusted to the process and by very efficient use of process chemicals, so that the new system consistently exploits the savings potential in the manufacturing of thin-film solar cells.

SINGULUS TECHNOLOGIES offers wet processing systems from R & D, through pilot use, to full production range 80, 150 and 300 MW.

For a higher throughput, several production machines can be combined to a large production complex.

Enabler in the CIS/CIGS Thin-Film Solar Cells Industry

Through its production systems, SINGULUS TECHNOLOGIES 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, SINGULUS TECHNOLOGIES believes the long-term prospects of the solar segment to be bright. Through its new system concepts and innovative processes, the company is promoting the development of solar technology, which will play an increasingly important role in the global energy mix.
