[0096]

[0097] 3,7-dibromo-10-(4-{2-[2-(2-methoxy-ethoxy)-ethoxy]-ethoxy}-phenyl)-10H-phenothiazine (0.95g, 2.1mmol), tributyl-thiophen-2 base-stannane (2.03g, 5.4mmol) and bis(triphenylphosphine)palladium dichloride (PdCl ， (PPh 3 ) 2 , 0.1 g, 0.13 mmol) was dissolved in 50 mL of dry tetrahydrofuran (THF), refluxed at 70° C., and stirred for 24 hours. After reacting weft, in water and chloroform (CHCl 3 ) in a 1:1 mixed solvent for separation and purification tests. After separating the organic layer through the separation and purification test process by the extraction method, the solvent was removed under reduced pressure. After removal of the solvent, silica gel column chromatography (chloroform: ethane, 1:3) was used to obtain a yellow solid product (0.759, 81.5%)

[0141] [Example 1] to [Example 15]: Manufacture of dye-sensitized solar cell

[0142] First, the conductive glass substrate (FTO; TEC8, Pilkington, 8Ωcm 2 , Thicknessof2.3mm) into ethanol, after cleaning, prepare commercial titanium dioxide (TiO 2 ) slurry (20nm, solarnonix), apply the prepared titanium dioxide slurry on the pre-cleaned glass substrate with a scraper, and burn it at 500°C for 30 minutes. The thickness of the fired titanium dioxide slurry is determined by Alpha-step IQ step meter (KLA Tencor) to measure. In order to use another titanium dioxide slurry as the scattering layer, the above-mentioned scattering layer was recoated with particles having a size of 250 nm, and then fired at 500° C. for 30 minutes. At 70°C, put the prepared titanium dioxide film into 0.04M titanium tetrachloride (TiCl 4 ) solution, soak for 30 minutes.

[0143] Next, to achieve dye adsorption, the annealed titanium dioxide electrode was placed in a dye solution (0.3 mM) containing th...

Abstract

The invention relates to a dye compound for dye sensitized solar cell and a solar cell comprising it, which can improve the efficiency of photovoltaic conversion.

Description

technical field [0001] The invention relates to an organic dye compound and a dye-sensitized solar cell comprising the compound, in particular to an organic dye compound for improving photoelectric conversion efficiency and a dye-sensitized solar cell comprising the compound. Background technique [0002] A solar cell is a device that uses the Photovoltaic Effect to convert light energy into electrical energy. Unlike other energy sources, it has unlimited resources and is an environmentally friendly energy source. Well-known silicon solar cells, dye-sensitized solar cells, etc. [0003] Due to its high price and difficulty in practical application, silicon solar cells also face many difficulties in improving efficiency. On the contrary, the manufacturing cost of the dye-sensitized solar cell is obviously lower than that of the existing silicon solar cell, so it has the possibility to replace the existing amorphous silicon solar cell. A dye-sensitized solar cell is a device ...
