| 摘要 |
A solar cell includes a substrate containing impurities of a first conductive type, an emitter region which is positioned at a first surface of the substrate and contains impurities of a second conductive type opposite the first conductive type to form a p-n junction along with the substrate, an anti-reflection layer positioned on the emitter region, a first electrode which is positioned on the anti-reflection layer and is coupled to the emitter region, and a second electrode which is positioned on a second surface of the substrate and is coupled to the substrate. A first area of the anti-reflection layer, which is positioned under the first electrode, has a plurality of openings. The first electrode couples to the emitter region exposed through the plurality of openings. |
