Tinned Copper Ribbon

Our high-efficiency welding strip uses TU1 oxygen-free copper wire with higher purity, copper content ≥ 99.99, and the copper base is thickened by about 10um to reduce the resistivity of the welding strip, improve the conductivity of the welding strip, and improve the power of the module (about 1W about). At present, it has been tested in small batches by JA Solar.
