Classification: CPC H | IPC H

Claim 0:
1. 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; and,
an electrode that is in contact with said carrier collection 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,
wherein said crystalline silicon solar cell further comprises: an anti-reflection layer provided on said carrier collection layer; said electrode passes through said anti-reflection layer and comes into contact with said carrier collection layer.
