摘要:
There are provided a dye-sensitized solar cell that achieves high photoelectric conversion efficiency, can be manufactured at low cost, and has excellent design properties and a method for manufacturing the dye-sensitized solar cell.Dye-carrying porous titanium oxide layers (2a to 2d) are formed on a transparent conductive substrate (1) such that a desired color is produced and a desired pattern is formed by selecting the type of a sensitizing dye, the thickness, the stacked structure, the particle size of the titanium oxide fine particles or, if the titanium oxide fine particles are composed of at least two types of titanium oxide fine particles having different particle sizes, the combination ratio of the at least two types of titanium oxide fine particles. The transparent conductive substrate (1) on which the dye-carrying porous titanium oxide layers (2a to 2d) have been formed and a transparent conductive substrate (3) on which a counter electrode (4) has been formed are bonded to each other through a sealant (5) such that the dye-carrying porous titanium oxide layers (2a to 2d) face the counter electrode (4). An electrolyte layer (6) is enclosed in the space between the dye-carrying porous titanium oxide layers (2a to 2d) and the counter electrode (4) and thus a dye-sensitized solar cell is manufactured.
