2BG, new technology in order to remove the silver paste from the cells backside.

13/07/2012

2BG S.r.l. introduces a new technology in order to remove the silver paste from the crystalline silicon solar cells backside. The silver pastes are considered a critical point in the solar cells cost/Watt decrease and in this direction a lot of steps forward have been made by 2BG Research & Development team. With 2BG S.r.l.’s own technology, called “Selective Plating”, it is possible to deposit directly in the aluminum the copper and the tin instead of silver pastes, achieving a saving up to 6 cents/wafer with an efficiency increasing up to 0,2%; the data is referred to cells with 6” dimensions. “Selective Plating” allows to reach an adherence 4 times higher than the standard one, with silver paste in the back part. This technology allows a return of investments in less than 1 year and gives the opportunity to use it in working plants, without changing the standard production.

The importance of the innovative “Selective Plating” was shared also by the technical-scientific commission of 200 worldwide experts, charged to organize one of the leading conference for the photovoltaic industry; the scientific publication will take place on the occasion of 27th European Conference, which takes place in Frankfurt from September 24th to 28th together with the EU PVSEC exhibition, exclusively dedicated to the photovoltaic field. The presentation, in collaboration with “La Sapienza” University of Rome (Italy), ENEA Casaccia Research Centre Rome (Italy), Rise Technology S.r.l. (Italy) is scheduled for Wednesday 26/09/2012 at 8:30 a.m. - Session N. 2CV.5.37, titled “Innovative and Low Cost Technique for Silver-Less Silicon Solar Cell”.
