[0329] (Preparation of Exemplary Compound D-1-1a)

[0330] Exemplary dye D-1-1a was prepared according to the method of the following flow.

[0331] (i) Modulation of compound d-1-2

[0332] Put d-1-125g, Pd(dba) 33.8g, triphenylphosphine 8.6g, copper iodide 2.5g, 1-heptyne (1-heptyne) 25.2g in triethylamine 70ml, tetrahydrofuran 50ml, at room temperature Stirring was carried out at 80° C. for 4.5 hours. After concentration, it purified by column chromatography to obtain 226.4 g of compound d-1-2.

[0333] (ii) Modulation of d-1-4

[0334] Dissolve d-1-36.7g in THF (tetrahydrofuran) (tetrahydrofuran) 200ml under a nitrogen atmosphere at -15°C, and add 2.5 equivalents of d-1-3's LDA (lithium diisopropylamide, two Lithium isopropylamide), stirred for 75 minutes. Thereafter, a solution in which d-1-215 g was dissolved in 30 ml of THF was added dropwise, stirred at 0° C. for 1 hour, and stirred overnight at room temperature. After concentration, 150 ml of water wa...

[0767] (1) Formation of the first photoelectric conversion layer

[0768] Using hard glass beads, 4.0 g of commercially available titanium oxide particles (manufactured by Imperial Chemical Co., Ltd., with an average particle diameter of 30 nm) and 20 ml of diethylene glycol monomethyl ether were dispersed for 6 hours by a paint shaker, and the particles were removed. Made of titanium oxide suspension. Next, use a scraper to coat the titanium oxide suspension on a glass plate with a tin oxide conductive layer attached in advance, pre-dry it at 100°C for 30 minutes, and then calcine it in an electric furnace at 500°C for 40 minutes. A glass plate with a titanium oxide film was obtained.

[0769] Separately, the pigment [cis-dithiocyano-N-bis(2,2′-bipyridine-4,4′-dicarboxylate) ruthenium, cis-dithiocyanine- N-bis(2,2'-bipyridyl-4,4'-dicarboxylic acid)ruthenium] was dissolved in ethanol.

Abstract

Disclosed is a metal complex dye which is characterized by having a ligand (LL1) that has a structure represented by general formula (I). (In general formula (I), R1 and R2 each represents a specific substituent; L1 and L2 each represents at least one group that is selected from among an ethenylene group, an ethynylene group and an arylene group, and is conjugated with R1, R2 and bipyridine; the ethenylene group and the arylene group may be substituted or unsubstituted; R3 and R4 each represents a substituent; n1 and n2 each represents an integer of 0-3; A1 and A2 each represents an acidic group or a salt thereof; and n3 and n4 each represents an integer of 0-3.)

Description

technical field [0001] The present invention relates to a metal complex dye excellent in durability and photoelectric conversion characteristics, a photoelectric conversion element containing semiconductor fine particles using the metal complex dye as a sensitizing dye, and a dye-sensitized solar panel using the photoelectric conversion element. Battery. Background technique [0002] As solar cells used in solar power generation, solar cells containing compounds such as monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, and copper indium selenide have been the main subjects of research and development, and some of them have been put into practical use. However, in order to widely spread these solar cells as household power sources, etc., these solar cells have the following problems that need to be overcome: it is difficult to manufacture cheaply or secure raw materials, and the energy recovery period (Energy Payback Time) is long. Wait....
