NEW TECHNOLOGY IN ORDER TO REMOVE THE SILVER PASTE FROM THE CELLS BACKSIDE Sep. 09, 2012The 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. ... more
