Embodiment 1

[0031] A kind of porous carbon material is used as the preparation method of the dye-sensitized solar cell of opposite electrode, comprises the following steps:

[0032] (1) Put the conductive glass (FTO) on the slide with a glass knife, then ultrasonically clean it with distilled water, after drying, ultrasonically clean it in acetone and ethanol solutions for 15 minutes, and soak the conductive glass in isopropanol solution for more than 24 hours for later use .

[0033] (2) Preparation of porous carbon counter electrode: 0.3 g of ZIF-8 powder was ground in a mortar for 3 hours, then 3 mL of n-butanol was added, and 2 mL of ZIF-8 colloid was coated by screen printing Put it on the FTO conductive glass, dry it at room temperature, put it in a tube furnace, and carbonize it under the protection of nitrogen at 400°C for 3 hours. After the temperature drops to room temperature, take it out and use it as the counter electrode of porous carbon material; carbonization It needs to ...

Embodiment 2

[0039] A kind of porous carbon material is as the preparation method of the dye-sensitized solar cell of counter electrode, and its step is identical with embodiment 1, and difference is:

[0040] Take a piece of soaked conductive glass and blow dry. Put 0.3 g of the synthesized ZIF-8 powder in a mortar, add 3 mL of n-butanol, and grind it in the mortar for 3 hours in order to disperse the aggregated ZIF-8 powder particles well. Then, 2 mL of ZIF-8 colloid was coated on the FTO conductive glass by screen printing, dried and carbonized in a tube furnace at 400 °C under nitrogen protection for 4 hours to obtain a porous carbon material counter electrode.

Embodiment 3

[0042] A kind of porous carbon material is as the preparation method of the dye-sensitized solar cell of opposite electrode, and its steps are identical with embodiment 1,2, and difference is:

[0043] Take a piece of soaked conductive glass and blow dry. Put 0.3 g of the synthesized ZIF-8 powder in a mortar, add 3 mL of n-butanol, and grind it in the mortar for 3 hours in order to disperse the aggregated ZIF-8 powder particles well. Then, 2 mL of ZIF-8 colloid was coated on the FTO conductive glass by screen printing, dried and carbonized in a tube furnace at 400 °C under nitrogen protection for 5 hours to obtain a porous carbon material counter electrode.

Abstract

The invention discloses a preparation method for a porous carbon material electrode for a counter electrode of a dye-sensitized solar cell. A porous carbon counter electrode which is prepared from a metal organic framework coordination compound under different carbonization conditions, and a squaric acid organic dye-sensitized TiO<2> porous thin film are assembled together; and the middle part is poured with a redox electrolyte to obtain the dye-sensitized solar cell taking the porous carbon material as the counter electrode. Photoelectric conversion efficiency of different cells can be obtained from different carbonization conditions, so that the photoelectric performance of the dye-sensitized solar cell can be optimized consequently; and meanwhile, the preparation method has the advantages of simple process, low cost, large area, no pollution and the like, so that the application of the dye-sensitized solar cell can be facilitated.

Description

[0001] This invention was funded by the general project (No. 14JCYBJC18000) of Tianjin Science and Technology Commission. technical field [0002] The invention belongs to the technical field of dye-sensitized solar cells, and in particular relates to a preparation method of a porous carbon material used for a sensitized solar cell counter electrode. Background technique [0003] With the increase of the world's population and the development of people's material life and industrialization, the shortage of energy has seriously restricted the further development of human civilization. Therefore, on the premise of not damaging the environment required for human health as much as possible, how to realize the sustainable development of human beings, the research and development and utilization of renewable energy have become the research focus and hot spot of scientific and technological workers all over the world. As a new energy source, solar energy is developing rapidly at pr...
