Abstract

Provided is a dye-sensitized solar cell element comprising at least one dye-sensitized solar cell, wherein the dye-sensitized solar cell includes a first base material including a transparent substrate, a second base material which faces the first base material, an annular sealing portion which bonds the first base material and the second base material, and an oxide semiconductor layer which is provided between the first base material and the second base material, wherein the second base material has a flexibility, wherein the second base material includes an annular bonding edge portion which is bonded to the sealing portion and a main body portion in an inner side of the bonding edge portion, and wherein a portion of the main body portion is a convex bending portion which is bent to be convex toward a side opposite to the first base material.

First claim

1 . A dye-sensitized solar cell element comprising at least one dye-sensitized solar cell,
wherein the dye-sensitized solar cell includes: a first base material including a transparent substrate; a second base material which faces the first base material; an annular sealing portion which bonds the first base material and the second base material; and an oxide semiconductor layer which is provided between the first base material and the second base material, wherein the second base material has a flexibility, wherein the second base material includes an annular bonding edge portion which is bonded to the sealing portion and a main body portion in an inner side of the bonding edge portion, and wherein a portion of the main body portion is a convex bending portion which is bent to be convex toward a side opposite to the first base material.

2 . The dye-sensitized solar cell element according to claim 1 , wherein the first base material is configured as a first electrode, and the second base material is configured as a second electrode.

3 . The dye-sensitized solar cell element according to claim 2 ,
wherein the oxide semiconductor layer is provided on the first electrode, and wherein a remaining portion of the main body portion includes a concave bending portion which is bent to be concave toward a side close to the oxide semiconductor layer.

4 . The dye-sensitized solar cell element according to claim 1 , wherein the convex bending portion is arranged at a position adjacent to the bonding edge portion.

5 . The dye-sensitized solar cell element according to claim 1 , wherein a bonding surface of the sealing portion with at least one of the first base material and the second base material includes:
a plurality of linear portions; and outward-swelling portions which swell toward outer sides of intersecting portions of the linear portions.

6 . The dye-sensitized solar cell element according to claim 5 , wherein the bonding surface of the sealing portion with at least one of the first base material and the second base material further includes inward-swelling portions which swell toward inner sides of the intersecting portions.

7 . The dye-sensitized solar cell element according to claim 1 ,
wherein the at least one dye-sensitized solar cell is a plurality of the dye-sensitized solar cells, wherein the transparent substrate is used as a common substrate of the plurality of the dye-sensitized solar cells, wherein the sealing portions of the two dye-sensitized solar cells adjacent to each other among the plurality of the dye-sensitized solar cells are integrated to constitute an integrated sealing portion, and wherein the bonding surface of the integrated sealing portion with at least one of the first base material and the second base material includes: a plurality of linear portions; and outward-swelling portions which swell toward outer sides of intersecting portions of the linear portions.

8 . The dye-sensitized solar cell element according to claim 7 , wherein the bonding surface of the integrated sealing portion with at least one of the first base material and the second base material further includes inward-swelling portions which swell toward inner sides of the intersecting portions.

9 . The dye-sensitized solar cell element according to claim 5 , wherein an edge portion of the outward-swelling portion has a circular arc shape.
