In a joint project between science and industry the German-based global market leader for high-tech stringer systems took part in developing the first lead-free PV system with glued ribbon technology. The strings for the new generation were produced on a Stringer TT1400ECA and have already proven their practical effectiveness.
For the ‘Lead-free Photovoltaics’ project the team, based at the Carinthian Tech Research (CTR) research institute and the Austrian Institute of Technology (AIT) also brought teamtechnik on board because of its pioneering position in solar bonding technology. In the jointly developed design, the solar cells are glued together using structured ribbons rather than being soldered - no lead required. This enables the lead content in a photovoltaic module to be reduced from about 20 grams to zero. Using glued ribbon technology and doing away with lead makes solar module manufacturing more environmentally sustainable and recycling easier. A pilot project using lead-free glued solar cell bonding has been set up in Villach, Austria and has proved itself to be practically feasible. The adhesive technology makes it possible to use structured LCR ribbons, which also allow a higher module output to be obtained.
The Energy Globe Award gives prizes to projects with a focus on sustainability and resource conservation. This environmental prize is awarded annually as a regional, national and international distinction. In Carinthia the prize was awarded in early May.
Teamtechnik specialists achieve best connection results;
The STRINGER TT1400 ECA makes the manufacture of solar cell strings by adhesive-bonding technology possible even in industrial mass production. teamtechnik has long been in demand internationally as a development partner in the solar field. Module manufacturers from many countries bring new cells and materials with them to teamtechnikin order to develop innovative process solutions together with its experts. Since the company entered the solar sector in 2004 this specialist in automation solutions has grown into a technology leader in the field of new cell types and manufacturing processes. The company invests constantly in the development of modern process and control technology and is a specialist in high performance stringers and layup applications.
