摘要：Fixing device for laser welding of electrical contacts in photovoltaic cells, which

presses the tab (3) of a photovoltaic cell solar module on the bus (2) of each photovoltaiccell, while they are being laser welded together. The device has an upper plate (5) onto alower one (6), each one of them featuring at least one opening (7) which are equal toeach other and have the same position. Those of the upper plates (5) are covered bytransparent panels (8), and a flexible and transparent membrane (10) is placed betweenthe two plates (5, 6). The silicon wafer (1) is inserted along with the tab (3) between thetwo plates (5,6), on the flexible membrane (10), being said membrane (10) inflated bycompressed air, exerting pressure on the silicon wafer (1), and fixing the tab (3) to theprinted bus (2).
