SINGULUS TECHNOLOGIES : will Present Reliable Technology & Machines for PV Cells at Intersolar North America

• Coating machine for rear side passivation of PERC for increased cell efficiency
• New PERC cells with higher efficiency levels announced
• 100 % PID-free solar cells produced on SINGULUS' turnkey line
• Proven CIGS production systems for all key processes

Kahl am Main, July 07, 2014 - In the Solar segment SINGULUS TECHNOLOGIES (SINGULUS) is a worldwide leading supplier for new production solutions for crystalline and thin-film solar cells, which with lower production costs increase the level of efficiency or achieve a higher level of efficiency.

For crystalline solar cells SINGULUS presents advanced production solutions for passivated rear silicon solar cells. The SINGULAR XP is specifically designed for the production capacity of a typical cell production line. In addition, SINGULUS' machine provides the advantage that the two layer systems required for the rear side passivation, aluminum oxide (AIOx) and silicon nitride (SiNx) can be applied without discontinuation of the vacuum. Due to its compact assembly the SINGULAR XP machine is ideally suited for the integration as an upgrade for existing cell production lines. Before coating the rear side it is smoothed with a wet-chemical glaze in a LINEA II glazing machine.

A new 21.2% world record efficiency for industrial silicon solar cells with screen-printed metal contacts was achieved earlier this year by the Institute for Solar Energy Research Hamelin (ISFH), Germany. The high efficient passivated emitter and rear cells (PERC) were developed and processed on industrial equipment within the joint research project High Screen funded by the German Federal Ministry of the Environment.

The solar cells produced on the SINGULUS turn-key line in Lithuania are 100 % PID-free due to SINGULUS specifically designed coating technology.

SINGULUS cooperates with thin-film solar cell manufacturers worldwide and develops processes, which improve the efficiency and reduce production costs.

SINGULUS is market leader for the wet-chemical cleaning applying CIS and CdTe processes. New plant concepts expand the value-added chain of the company in the area of thin-film solar technology. SINGULUS offers modern production systems for CIS/CIGS & CdTe thin-film solar panels.

With sputtering & evaporation, the selenisation for an optimized CIGS absorber formation as well as wet processing solutions SINGULUS already covers two thirds of the required machines of a CIS/CIGS modules production with its range of machines.
