Abstract:
A bypass-function added solar cell comprising:a first-conductive-type first region; a second-conductive-type second region formed on a light-receiving surface side of the first-conductive-type first region; a first-conductive-type third region which is formed at part of a pn junction plane where the first region and the second region abut each other so that the third region is provided over the first region and the second region and projects into both the first region and the second region, the third region being higher in impurity concentration than the first-conductive-type first region; and wherein the first-conductive-type third region projects into the second region but does not reach a surface of the second region that is closest to light-receiving surface side electrodes of the solar cell.
