Abstract
A back-contact solar cell includes groove area and non-groove area that are alternately disposed on the shady face of silicon chip. At a predetermined position in the groove area, a first doped layer has an extending portion that extends above the groove area, and the second doped layer has a wrapping portion which covers and recombines with the first surface of the extending portion. No silicon wafer part is provided on the side of the position where the wrapping portion recombines with the first surface, and the edge recombination generated by the boundary area between them has a relatively narrow impact range, which can effectively improve the efficiency with a higher filling factor.
