Dye-sensitized solar cell and method of manufacturing the same

A method of manufacturing a dye-sensitized solar cell, comprising:

• a first step of obtaining a power generation layer by forming a semiconductor layer on a first main surface of a transparent electrode, allowing a photosensitizing dye to be absorbed onto the semiconductor layer, and forming an electrolyte layer in a gel-like state or in a solid-like state on the semiconductor layer with the photosensitizing dye absorbed;
• a second step of forming a counter electrode on a main surface of the power generation layer in a manner that all the side surfaces of the counter electrode and all the side surfaces of the power generation layer are positioned coplanar, respectively, and an electrode extraction region of the counter electrode overlaps with a main surface of the power generation layer in a top view, wherein, in a top view, all side surfaces of the transparent electrode are positioned coplanar with those of the counter electrode and the power generation layer, except for a corner portion connecting two adjacent side surfaces of the transparent electrode, where the counter electrode and the power generation layer do not cover the corner portion so that the first main surface of the transparent electrode is exposed solely at the corner portion, forming an electrode extraction region of the transparent electrode, wherein the electrode extraction region of the counter electrode and the electrode extraction region of the transparent electrode face in a same direction which is a thickness direction of the dye-sensitized solar cell;
• and
• a third step of forming a sealing layer extending from one of the transparent electrode and the counter electrode to the other so as to cover the side surfaces of the power generation layer.
