Problems solved by technology

However, if air bubbles remain inside the tubular container 1, residual air bubbles are sandwiched between the photoelectrode 4 and the electrolyte solution 6, and the contact between the photoelectrode 4 and the electrolyte solution 6 becomes insufficient, and the photoelectrode 4 is loaded on the photoelectrode 4. The sensitizing pigment is not fully reduced, and the power generation efficiency decreases.

Embodiment Construction

[0051] FIG. 1(A) is a side sectional view showing the whole of the dye-sensitized solar cell of the present invention, and FIG. 1(B) is an AA sectional view thereof.

[0052] On the inner surface of the main body 2 of the tubular container 1, a collecting electrode 3 made of a transparent conductive film and a photoelectrode 4 laminated thereon are provided. The collecting electrode 3 is provided so as to extend from the main body 2 to one sealing portion 22 , while the above-mentioned photoelectrode 4 exists only in the main body 2 and does not extend to the sealing portion 22 .

[0053] In addition, in the main body portion 2 of the tubular container 1 , the coil-shaped counter electrode 5 is arranged so as not to contact the photoelectrode 4 .

[0054] A metal tube 8 is sealed in one sealing portion 21 of the above-mentioned tubular container 1 . The sealing adopts the shrink sealing technique in lamp manufacturing technology, and the metal tube 8 constituting the outer co...

Abstract

The invention provides a dye-sensitized solar cell including: a translucent tube-shaped vessel having sealing portions at both ends thereof, a photoelectrode, a collective electrode, and a counter electrode, the photoelectrode, the collective electrode, and the counter electrode being provided in the interior of the tube-shaped vessel; external leads electrically connected respectively to the collective electrode and the counter electrode, and electrolytic solution filled in the interior of the tube-shaped vessel, wherein remaining of air bubbles cause by evaporation of the electrolytic solution when hermetically sealing the tube-shaped vessel after having filled with the electrolytic solution is avoided, whereby preferable power generation efficiency is achieved. At least one of the external leads is formed of a metallic tube, the metallic tube is sealed by the sealing portion, and a projecting end portion of the metallic tube is hermetically sealed.

Description

technical field [0001] The present invention relates to a dye-sensitized solar cell that converts light energy into electrical energy, and particularly relates to a dye-sensitized solar cell in which an electrolytic solution is sealed in a translucent tubular container. Background technique [0002] Conventionally, solar cells for converting light energy into electric energy have been actively researched and developed as environmentally friendly and clean energy sources. Among them, dye-sensitized solar cells have attracted attention as solar cells with high photoelectric conversion efficiency and low cost, and various proposals have been made. [0003] One example is Japanese Patent No. 4840540 (Patent Document 1). In this dye-sensitized solar cell, an electrolyte solution is sealed in a light-transmitting tubular container, and a porous substance adsorbed with a dye is arranged in the container. A photoelectrode made of a semiconductor and a counter electrode facing the p...
