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 at least one edge secondary grid line has a width greater than the middle secondary grid line. The solar cell unit also comprises a plurality of conductive wires spaced apart from each other. The plurality of conductive wires intersects and is connected with the secondary grid lines.
