Photoelectric Conversion Element And Photoelectric Conversion Element Module Comprising Same
A photoelectric conversion element includes a frame-shaped insulating sealing part that is disposed between the plurality of first electrodes and the cover and defines a space inside the photoelectric conversion element, a photoelectric conversion part formed on an upper surface of a first electrode in the space; a second electrode formed in the space, which includes a flat portion and a bent portion, and insulates the photoelectric conversion part from the second electrode, an inter-cell insulating part that insulates the first electrode from the second electrode, a carrier transporting part with which the space is filled, and an insulating bonding part that has at least a portion positioned between the porous insulating part and the cover and is brought into contact with the inter-cell insulating part and with a portion of the flat portion so as to bond the inter-cell insulating part and the second electrode to each other.

- 1. A photoelectric conversion element comprising:
a transparent substrate having a light-receiving surface; a cover disposed to face the transparent substrate; a plurality of first electrodes formed on a surface of the transparent substrate facing the cover; a frame-shaped insulating sealing part that is disposed between the plurality of first electrodes and the cover and defines a space inside the photoelectric conversion element; a photoelectric conversion part formed on an upper surface of a first electrode among the plurality of first electrodes in the space; a second electrode formed in the space, which includes a flat portion that faces an upper surface of the photoelectric conversion part and a lower surface of the cover, and a bent portion that is bent at an end of the flat portion toward another first electrode adjacent to the first electrode among the plurality of first electrodes and is electrically connected to the another first electrode; a porous insulating part that is positioned between the photoelectric conversion part and the second electrode, and insulates the photoelectric conversion part from the second electrode; an inter-cell insulating part that is in contact with at least a portion of an outer circumference of the photoelectric conversion part and insulates the first electrode from the second electrode; a carrier transporting part with which the space is filled; and an insulating bonding part that has at least a portion positioned between the porous insulating part and the cover and is brought into contact with the inter-cell insulating part and with a portion of the flat portion so as to bond the inter-cell insulating part and the second electrode to each other.
