摘要： The present invention relates to an electroconductive substrate including a base material and a metal wiring made of at least either of silver and copper, and the electroconductive substrate has an antireflection region formed on part or all of the metal wiring surface. This antireflection region is composed of roughened particles made of at least either of silver and copper and blackened particles finer than the roughened particles and embedded between the roughened particles. The blackened particles are made of silver or a silver compound, copper or a copper compound, or carbon or an organic substance having a carbon content of 25 wt% or more. Then, the antireflection region has a surface with a center line average roughness of 15 nm or more and 70 nm or less. The present inventive electroconductive substrate is produced by forming a metal wiring from an metal ink that forms roughened particles, followed by application together with a blackening ink containing blackened particles. The metal wiring on the electroconductive substrate of the present invention has suppressed light reflection, and its presence is hard to view.

摘要： The present invention relates to a method for recovering Ru complex dye from a used dye solution containing a polypyridine Ru complex as a Ru complex, the used dye solution having been discharged from a step of manufacturing a dye-sensitized solar cell, the method including the steps of:
(a): filtering the used dye solution to separate and remove solid content.
(b): bringing a separating solvent including an ether-based solvent indicated by a chemical formula C x H (2x+1) -O-C y H (2y+1) (x = 1 to 4 and y = 1 to 4, with the proviso that x + y ≥ 4) or an alkane-based solvent indicated by a chemical formula C x H (2x+2) (x = 5 to 7) into contact with the used dye solution to separate the Ru complex dye.

摘要： The present invention relates to a dye-sensitized solar cell, in which there is applied an asymmetric ruthenium complex where two thiocyanate groups and two bipyridine ligands which are different from each other are coordinated with a Ru metal, as a photosensitizing dye, and there is applied an organic compound where two carboxyl groups are coordinated with a hydrocarbon group which has a linear saturated hydrocarbon having 1 or more and 3 or less carbon atoms as a main chain, as a co-adsorbent. The present invention contributes to the improvement of power generation efficiency under a low illumination circumstance, such as an indoor living room, to extend the use of the dye-sensitized solar cell which is excellent in design property. The dye-sensitized solar cell according to the present invention exhibits a high power generation efficiency even under a low illumination circumstance, such as an ordinary living room indoors.
