The Heraeus Photovoltaics Business Unit has launched two new high efficiency front-side metallization pastes for standard to ultra-lightly doped emitter cells – the SOL9620 Series and SOL9621 Series.
Applied Materials has entered the solar wafer inspection market with ‘Applied Vericell’ system designed to fully-automate in-line wafer inspection to address the quality limitations of manual review, with the capability to automatically predict wafer cell efficiency through photoluminescence (PL) technology. The Vericell system is being introduced at SNEC 2014 in Shanghai, China.
centrotherm is highlighting low-pressure diffusion system at SNEC 2014, which it claims can offer up to 40% per wafer for solar cell emitter formation. The cost reductions are attributed to almost a doubling of the systems wafer throughput to more than 140MW per year and overall lower media consumption.
ROFIN-BAASEL Lasertech is launching a new upgraded version of its production proven ‘Dual Line c-Si’ laser processing system that provides improved productivity and lowers processing costs in volume production of next-generation PERC (Passivated Emitter and Rear Cells) solar cell design. The latest Dual Line c-Si™ modular platform will be unveiled at the forthcoming SNEC 8th 2014, International Photovoltaic Power Generation Exhibition, being held in Shanghai, China May 20-22, 2014 at the Shanghai New International Expo Center. ROFIN-BAASEL Lasertech’s booth is located in Hall 3, 615.
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.
