- Coating Machine for Rear Side Passivation of PERC: with the SINGULAR XP cell efficiency increased by up to 1 %
- New PERC cells with higher efficiency levels announced
- TENUIS Development Machine for Buffer Layer Deposition shown at the booth
- Proven CIGS Production Systems
With the development machine of the TENUIS series reproducible process results can be easily transferred to an industrial production volume. The industrial manufacturing machines of the TENUIS type have a modular cluster build 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 Sputtering and 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.
For crystalline solar cells SINGULUS presents at the Snec 2014 an advanced production solution 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. For the rear side contacting through a laser process, SINGULUS is closely cooperating with a partner.
A new 21.2% world record efficiency for PERC was achieved by the Institute for Solar Energy Research, Emmerthal, Germany, within the research project High Screen funded by the German Federal Ministry of the Environment in collaboration with several project partners.
