| 摘要 |
A solar cell includes a substrate, a first lightly-doped region, a second lightly-doped region, a second heavily-doped region, a first electrode and a second electrode. The first lightly-doped region having a first doping type is disposed in a first surface of the substrate. The second lightly-doped region and the second heavily-doped region having a second doping type different from the first doping type are disposed in a second surface of the substrate. The first electrode is disposed on the first surface of the substrate, and the second electrode is disposed on the second surface of the substrate. |
