Patent ID: 8049099

Claim:
A first solar cell and a second solar cell electrically connected in an arrangement direction, each cell comprising an n finger electrode and a p finger electrode alternately arranged on a projection plane parallel to a main surface of a substrate, wherein each solar cell comprises an n-side bus bar electrode connected to the n finger electrode and insulated from the p finger electrode and a p-side bus bar electrode connected to the p finger electrode and insulated from the n finger electrode, wherein the n-side bus bar electrode and the p-side bus bar electrode are parallel to each other and provided on a same main surface side of the substrate, intersect with the n finger electrode and the p finger electrode respectively on the projection plane, and the bus bar electrodes have a non-zero slope angle relative to the arrangement direction and configured to allow adjacent solar cells to be connected in series without inverting the polarity of the solar cell or without inverting the direction of the solar cell, and wherein a bus bar electrode from the first solar cell is in the same direction as and connects to a bus bar electrode from the second solar cell.
