SOLAR CELL AND SOLAR CELL MODULE

摘要

A solar cell includes: a base substrate that has a principle surface; a first semiconductor layer provided in a first region on the principle surface; a second semiconductor layer provided in a second region on the principle surface; an n-side electrode provided on the first semiconductor layer; a p-side electrode provided on the second semiconductor layer; and grooves that separate the n-side electrode and the p-side electrode from each other. The respective widths of the grooves in a direction in which the n-side electrode and the p-side electrode are spaced apart are set to be wider in the outer peripheral region than in the inner region.

1. A solar cell comprising:
a base substrate that has a principle surface; a first semiconductor layer that is provided in a first region on the principle surface; a second semiconductor layer that is provided in a second region, which is different from the first region, on the principle surface; an n-side electrode that is provided on the first semiconductor layer; a p-side electrode that is provided on the second semiconductor layer; and a groove that separates the n-side electrode and the p-side electrode from each other, wherein the principle surface has an outer peripheral region provided along the outer periphery of the principle surface and an inner region provided inside the outer peripheral region, and wherein the width of the groove in a direction in which the n-side electrode and the p-side electrode are spaced apart is set to be wider in the outer peripheral region than in the inner region.
