Abstract:
A solar cell unit comprises a cell. The cell includes a cell substrate and a plurality of secondary grid lines disposed on a front surface of the cell substrate. The secondary grid lines comprises an edge secondary grid line adjacent to an edge of the cell substrate and a middle secondary grid line disposed inside of the edge secondary grid line. The secondary grid line comprises a welding portion. At least one welding portion of the edge secondary grid line has a projection area in the cell substrate larger than a welding portion of the middle secondary grid line. The solar cell unit also comprises a plurality of conductive wires spaced apart from each other and welded with the secondary grid lines in the welding portion.
