WIPO Patent Application WO/2015/182525
Kind Code:
A1
Abstract:
A solar cell element (1) according to one embodiment of the present invention is provided with: a p-type semiconductor layer (21); an n-type semiconductor layer (22) that is arranged on a first main surface of the p-type semiconductor layer (21); an insulating layer (3) that is arranged on a first main surface of the n-type semiconductor layer (22) and has a through hole (T) which penetrates the insulating layer in the thickness direction; an electrode (4) that is arranged on a portion of the first main surface of the n-type semiconductor layer (22) within the through hole (T) of the insulating layer (3) and has a thickness larger than that of the insulating layer (3); and a conductor layer (5) that is arranged on a first main surface of the insulating layer (3) so as not to be in contact with the electrode (4) and has a work function smaller than that of the n-type semiconductor layer (22).
