All the main players of the PV market are focusing in increasing their solar cell efficiency by combining a significant reduction of the production cost, 2BG would like to share its last ongoing R&D technology that removes the use of silver paste by a new process using an absolutely new plating concept. The research project has started at the beginning of 2010 through the collaboration with Rise Technology Srl, Italian company founded by researchers of “La Sapienza” University of Rome. Now we are proud to demonstrate that theory is effective applicable in the PV industry, anticipating the forecasted removal of silver past for the 2015 like said from “The Crystalline Silicon PV Technology and Manufacturing”, group of SEMI, confirming 2BG potentiality not only as a common supplier for module equipment. 2BG has organized a conference reserved to the main cell producers to illustrate this latest technology for cells production and giving them the possibility to see the principle of the theory at work, at its booth during the 26th EU PVSEC. The conference will held in presence of the major expert in the PV market, Dr. Mario Tucci of ENEA company, and Prof. Marco Balucani of “La Sapienza” University of Rome. Don’t lose the opportunity to change your future strategy, being more competitive and innovative!

2BG Srl, in collaboration with SCHLENK, has developed the technology to interconnect automatically the solar cells with ribbon SCHLENK LHS in its own Tabber&Stringer. This system called “DRS” (Double Ribbon Soldering) ensures the maximum flexibility in the photovoltaic modules production in fact, it allows to use in addition to the common ribbon, even the SCHLENK LHS and exploit all its benefits in terms of efficiency. “DRS” has been developed for being installed on 2BG Tabber&Stringer models, already on stream by its customers.

2BG s.r.l. extends and strengthens its product line with the automation of the welding process of string bussing in order to satisfy the most exacting requirements for quality and throughput. IC200AR is the ideal solution to remove all problems and restrictions of manual welding, ensuring repeatability, precision and stability of results. This in-line system based on advanced technologies, result of the remarkable know-how and strengthened experience, is constituted by a robotic workstation that prepares the measure, welds ribbon bussing strings to complete the electrical circuit before the module lamination. Special attention was paid for the choice and the integration of welding technology and the vision system with the aim to ensure the best combination of performance and reliability reaching ciclye time of 80 sec for each of 72- cell module. With the new bussing system, solar cells are not subject to mechanical stress thanks to the high quality of welding without heat and precision for identifying the welding point. The workstation provides a flexible process with reduced maintenance charges and low operative costs. The integration of the new system allows to decrease the cost per watt in a remarkable way in the assembly panel.
