Sono-Tek unveils deposition system for thin film solar cells
The system is ideal for applying buffer layers onto thin-film solar cells (CdS) and active layers such as CIGS and CdTe.
Sono-Tek Corporation based in Milton NY, USA plans to exhibit at SemiCon-Intersolar 2011 July 12-14 in San Francisco, CA in booth #2631 (South Hall).
The firm will display its ExactaCoat Tabletop Coating System along with working demonstrations of its patented precision ultrasonic spray nozzles.
The ExactaCoat Tabletop Coating System is a fully enclosed programmable XYZ motion system designed for depositing uniform thin-film coatings for electronics and solar applications, including photoresist deposition and various thin-film solar cell coatings.
Particularly suitable for deep well topography coatings, the ExactaCoat is a full coating solution for R&D and low-volume production applications such as depositing photoresist onto wafers and MEMs. The system is also ideal for applying buffer layers onto thin-film solar cells (CdS), active layers such as (CIGS, CdTe), phosphoric doping, organic solar cell coatings, and fluxing of solder bus lines.
The ExactaCoat can be tailored with a number of customisable options including nozzle tilt, dual nozzle, camera, laser pointer, low oxygen atmosphere, and rod coating attachment. Additionally, the ExactaCoat can be configured with any of Sono-Tek’s precision ultrasonic atomising nozzles to produce highly uniform targeted thin-film coatings with very little overspray and exceptional non-clogging repeatable performance with significant savings in spray materials, maintenance and cleanup costs.
