Abstract: A solar cell unit comprises a cell. The cell includes a cell substrate and a secondary grid line disposed on a front surface of the cell substrate. The solar cell unit also comprises a conductive wire intersecting and welded with the secondary grid line. The secondary grid line has a width in a welding position with the conductive wire greater than a width thereof in a non-welding position.
