Abstract: A solar cell array comprises a plurality of cells, adjacent cells connected by a metal wire. At least one metal wire extends reciprocally between a surface of a first cell and a surface of a second cell adjacent to the first cell to form a plurality of conductive wires. The number of the conductive wires is n, y−y×20%≤n≤y+y×20%, in which n is an integer and y=4.0533X−1.28/1562*A*B, in which X is a diameter value of the metal wire with mm as a unit, 0.1≤X≤0.5, A and B representing length and width of the cell with mm as the unit. The cells comprise secondary grid lines disposed on front surfaces thereof. The conductive wires are welded with the secondary grid lines by a welding layer.

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.
