Classification: CPC H | IPC H

Claim 6:
7. A crystalline silicon solar cell, including:
a crystalline silicon substrate,
a passivation layer that is provided on a side of said crystalline silicon substrate and has a through hole,
a carrier collection layer that is provided on said passivation layer;
an electrode that is in contact with said carrier collection layer;
a doped layer that is provided on the other side of said crystalline silicon substrate; and,
a second electrode that is in contact with said doped layer,
wherein, said carrier collection layer has a conductivity type that is opposite to that of said doped layer,
wherein, said carrier collection layer comes into contact with the crystalline silicon substrate via the through hole on said passivation layer,
wherein said electrode has a portion corresponding to the through hole on said passivation layer and the portion of said electrode corresponding to the through hole is located inside the through hole, and wherein there is a certain distance between the end of the portion of said electrode located inside the through hole and the crystalline silicon substrate; and
the certain distance is less than the depth of the through hole.
