Singulus Technologies AG (Kahl am Main, Germany) has taken its product family of vacuum coating systems for use in solar photovoltaic (PV) technology to the next development level, the company announces.

Singulus also introduced and installed inline sputtering system for the requirements in the PV industry for CIGS & CdTe thin-film solar cell production as well as tasks for the manufacturing of heterojunction cells.

The systems are available with vertical as well as horizontal substrate transport and can be configured for various substrate sizes and are ideally suited for challenging layer stacks and flexible product mixes.

Typical applications include e.g. anti-reflection and barrier coatings, buffer and precursor layers such as copper-gallium, indium, and i-ZnO, but also different metallic layers like Mo, Al, Cu, Ag, and NiV etc. as well as transparent conductive oxide layers like ITO, AZO which are necessary for new heterojunction cell technology.

The systems use an inline process in which the substrates are transported on a special designed conveyor system on flat carriers through the system. The carriers can be configured flexibly for different substrate formats and materials e.g. solar wafers. Different automation options for loading and unloading are available.

The VISTARIS system with vertical substrate transport and the HISTARIS system with horizontal transport had been designed to enhance the efficiency of thin-film solar cells, while cutting production costs by using the state-of-the-art technologies.

Through its PV production systems, SINGULUS TECHNOLOGIES supplies wet-chemical processing, coating machines 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, the company notes.

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 believes the long-term prospects of the solar segment to be bright.
