SOLAR CELL AND METHOD FOR MANUFACTURING SUCH A SOLAR CELL. |
摘要 |
A solar cell including a semiconductor substrate, having a front side surface for receiving radiation and back-side surface providing a first junction structure in a first area substrate portion and with a second junction structure in a second area substrate portion. The second area portion borders the first area portion. The first junction structure includes a first conductivity type semiconductor layer covering the first area portion. The second junction structure includes a second conductivity type semiconductor layer covering the second area portion. The second junction structure, second conductivity type semiconductor layer partially overlaps the first junction structure, first conductivity type semiconductor layer, with the overlapping second conductivity type semiconductor layer portion being above a first conductivity type semiconductor layer portion while separated by a first dielectric layer. The first conductivity type semiconductor layer portion under the overlapping second conductivity type semiconductor layer portion directly contacts the semiconductor substrate surface. |
