GT Advanced Technologies (GTAT) has announced an innovative cell metallisation and interconnect technology, dubbed ‘Merlin’ that is expected to provide substantial savings in both the manufacture and installation of solar modules. A key component of the new technology includes a flexible grid that replaces conventional two and three silver bus bars, while significantly reducing solver paste consumption.
Dow Corning’s silicone-based, next-generation Electrically Conductive Adhesive (ECA) ‘PV-5802’ will be used in Tianwei New Energy’s Metal Wrap Through (MWT) module production line, developed by ECN of the Netherlands. PV-5802 is said to provide improved electrical properties and stability, which will greatly enhance the electrical performance, reliability and durability of MWT modules.
3D-Micromac has developed a novel, highly productive laser system for opening the rear sides of PERC cells. Innovative on-the-fly technology makes it possible to achieve an improved cost-benefit ratio. The system is modular, combinable with different laser-source technologies, and achieves a typical efficiency increase up to one percentage point.
VINSPEC solar VCOFLC1 camera system from VITRONIC enables exact and reliable front print and color inspection.
Virtual Industries, a supplier of manual vacuum handling solutions, has made available its new general-purpose wafer vacuum handling tool, ‘WAFER-VAC’ system with 8” molded wafer tip (WV-9000-MW8).
Start-up Sol Voltaics has unveiled ‘SolInk’, which is claimed to be an economical nanomaterial that promises to increase the efficiency of crystalline silicon or thin-film solar modules by up to 25% or more. Gallium arsenide nanowires are fabricated via a high-throughput process called ‘Aerotaxy’ invented by company founder and Lund University professor Lars Samuelson.
PSE AG has developed a new test stand, Degratest Labtool, designed for the testing of the light-induced degradation (LID) effect on silicon solar cells. The testing technology monitors and records degradation effects, and offers manufacturers and research institutions a fast and reliable tool for testing and developing solar cells. The LID test system was developed at ISC Konstance.
Datapaq has launched a tailored version of its SolarPaq temperature profiling system for contact paste drying processes.
Scanlab has broadened its offering with ‘SCANalign,’ a vision system tailored specifically to the demands of laser processing steps used in solar cell fabrication steps.
Meyer Burger’s patented ‘SmartWire Connection Technology’ (SWCT) is designed to replace conventional silver-based busbars on solar cells using thin copper wires on both sides of the cell. Typically, 30 very fine copper wires are used for cell connection generating up to 2,000 contact points per cell that provide 5% higher power output compared to best-in-class 3BB (three busbar) technology, while reducing production costs.
