Embodiment 1

[0035] The composite PEDOT counter electrode is based on FTO conductive glass 1, and the mass ratio of ATO nano conductive powder, terpineol, ethyl cellulose, lauric acid and ethanol is 1:6:0.3:0.1:15 and mixed evenly to obtain ATO slurry. Take 100 microliters of ATO slurry, set the speed of the homogenizer to 2000 rpm, and last for 30 seconds to obtain an ATO film with a uniform thickness on the conductive glass substrate 1 . Subsequently, the prepared ATO membrane was sintered at a temperature of 450 degrees Celsius for 30 minutes to remove the non-conductive powder in the ATO membrane to obtain a support layer 2 composed of an ATO porous membrane.

[0036] 50 mg of DBEDOT monomer and the sintered ATO porous membrane support layer 2 were put into a conical flask with a volume of 100 ml, and nitrogen gas was introduced as a protective gas, and then the conical flask was sealed. The entire system was heated at 70 degrees Celsius for 3 hours to obtain a PEDOT porous membrane, ...

Embodiment 2

[0040] The composite PEDOT counter electrode is based on ITO conductive glass 1, and the mass ratio of ATO nano conductive powder, terpineol, ethyl cellulose, lauric acid and ethanol is 1:6:0.3:0.1:15 and mixed evenly to obtain ATO slurry. Take 100 microliters of ATO slurry, set the speed of the homogenizer to 2000 rpm, and last for 30 seconds to obtain an ATO film with a uniform thickness on the conductive glass substrate 1 . Subsequently, the prepared ATO membrane was sintered at a temperature of 500 degrees Celsius for 20 minutes to obtain an ATO porous membrane as the supporting layer 2 .

[0041] 100 mg of DBEDOT monomer and the sintered ATO porous membrane were put into a conical flask with a volume of 200 ml, and the conical flask was evacuated and sealed. The entire system is heated at 50 degrees Celsius for 24 hours to obtain a PEDOT porous membrane, which constitutes the conductive polymer membrane 3 . Finally, the composite PEDOT counter electrode was obtained. A...

Abstract

The invention provides a dye-sensitized solar cell composite pair electrode and a preparing method thereof, and belongs to the technical field of solar cells. The structure of the composite pair electrode is that conductive glass is used as a base (1), a supporting layer (2) made of an antimony and tin oxide material and of a porous membrane structure is arranged on the base (1), and a conductive polymer film (3) made of a 3, 4-ethylenedioxythiophene material is arranged on the surface of the supporting layer (2). The preparing method of the dye-sensitized solar cell composite pair electrode comprises the steps of allocating antimony and tin oxide slurry, preparing the supporting layer 2 and carrying out vapor deposition. By means of the dye-sensitized solar cell composite pair electrode, in the aspect of raw materials, the problem that a platinum electrode is high in price is avoided, the dye-sensitized solar cell composite pair electrode with high conductivity and high catalytic activity replaces the platinum pair electrode and has economic advantages, the electrode preparing process of the antimony and tin oxide porous membrane and porous 3, 4-ethylenedioxythiophene composite pair electrode is simple, operation is simple, and the dye-sensitized solar cell composite pair electrode is suitable for being produced in large scale.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, and relates to a novel dye-sensitized solar cell porous PEDOT composite counter electrode and a preparation method thereof. Background technique [0002] For a long time, the counter electrode of dye-sensitized solar cells is mainly platinum electrode, which has the advantages of good conductivity and high catalytic activity. However, because platinum is a rare metal and is expensive, the practical application of dye-sensitized solar cells has been restricted. At present, researchers are looking for new materials that can replace platinum electrodes, and the conductive polymer PEDOT is an ideal material for the counter electrode due to its good film-forming properties, catalytic activity and conductivity. The methods for preparing PEDOT are mainly oxidative polymerization and electrochemical polymerization. The disadvantage of oxidative polymerization is that the obtained produ...
