SOLAR CELL |
| 摘要 |
Discussed is a solar cell including a semiconductor substrate comprising a base region, an emitter region having a conductive type opposite to that of the base region, and a back surface field region having the same conductive type as the base region and a higher doping concentration than the base region, and a first electrode and a second electrode respectively connected to the emitter region and the back surface field region, wherein the base region has a specific resistance of 0.3 Ωcm to 2.5 Ωcm. |
