With its new SUPERSCAN IV-15 WAFER 2-axis deflection unit, RAYLASE GmbH offers a sophisticated solution for challenging industrial applications. Predestinated applications include, in particular, the structuring of wafers in the solar industry.
This special version of the SUPERSCAN-IV-15, with its ultra-high speed, is designed to meet the high-performance requirements that apply to the manufacturing of wafers, where the highest possible angular velocity is essential.
One trend-setting application for the SUPERSCAN-IV WAFER is the production of photovoltaic wafers using the innovative PERC technique. The International Technology Roadmap for Photovoltaics (ITRPV) predicts that this technology will have a global market share of over 45% by 2025. PERC wafers consist of solar cells with a passivated emitter and passivated rear side. They are capable of reflecting light at wavelengths above 1,180 nm, resulting in less heat development in the cell and a significantly higher efficiency of conversion into usable energy.
RAYLASE has optimised the SUPERSCAN IV-15 specifically for these applications to enable the high-quality yet time- and cost-efficient production of these powerful PERC photovoltaic wafers. The SUPERSCAN IV-15's model-based, digital control offers extremely high speeds of up to 200 rad/s.
The robust, water-cooled master block design enables applications at up to 2 kW laser power when quartz mirrors are used. The deflection unit can be controlled digitally both via the XY2-100 enhanced protocol and via the SL2-100 protocol. The input aperture is 15 mm. Lenses with optimised holders and scan mirrors are available for all standard laser types, wavelengths, power densities, focal lengths and processing areas. Custom solutions can also be provided.
