SOLAR CELL AND METHOD FOR MANUFACTURING SOLAR CELL

摘要

[ABSTRACT]:[Problem] Provided is a solar cell in which recombination of minority carriers is reduced and conversion efficiency is thereby improved. [Solving Means] The invention is solar cell 1 comprising: semiconductor substrate 10n of a first conductivity type; first semiconductor layer 20n having a first conductivity type; second semiconductor layer 30p having a second conductivity type; first electrode 50n; second electrode 50p; and insulating layer 40. First semiconductor layer 20n and second semiconductor layer 30p are formed on rear surface 12. When one end portion of insulating layer 40 which is formed on first semiconductor layer 20n and which is on a side close to first electrode 50n is defined as first insulating-layer end portion 45a and another end portion of insulating layer 40 on a side close to second electrode 50p is defined as second insulating-layer end portion 45b in arrangement direction x, a distance from end point 39 of second-semiconductor-layer end portion 37 in contact with rear surface 12 to second insulating-layer end portion 45b in arrangement direction x is shorter than a distance from end point 39 to first insulating-layer end portion 45a in arrangement direction x.
