August 11, 2011 — SINGULUS TECHNOLOGIES subsidiary SINGULUS STANGL SOLAR released a cluster tool design of its TENUIS wet-chemical coating line for copper indium gallium di-selenide (CIGS) thin film solar module production. The cluster design is meant to save floor space (30% less room than the first generation TENUIS), and also enables simultaneous one-side coating of two substrates. Dosing and temperature control improvements reduce process time by up to 20% compared to the first generation TENUIS. Several production machines can be combined into a large production complex. The cluster design is inherently modular, enabling faster project ramp-up times. A module for alternative processes can be run independently in the production line. Alternative coating materials, such as ZnS, can be used. SINGULUS makes equipment for solar and optical disc manufacturers.
