Embodiment Construction

[0020] The following examples describe the present invention in more detail.

[0021] (1) Preparation of MoO by hydrothermal method 3 nanobelt. Take 7.2g of ammonium molybdate annealed particles, and 55mL of H 2 o 2 Mix and stir for more than 6 hours, then add 27mL of concentrated nitric acid to the solution and stir for 2 hours, then add an appropriate amount of water and continue stirring for a period of time, let the obtained solution stand for a week, and finally pour the solution after standing for a week into the autoclave 170 degrees Celsius reaction for 45 hours to get MoO 3 nanobelt;

[0022] (2) Preparation of MoO by cold water bath method 3 ·PANI. Take 0.15g of MoO obtained 3 Dissolve the nanoribbons in 100mL1mol / L hydrochloric acid, stir for a period of time, then add the cooled 0.3mL aniline and 100mL1mol / L hydrochloric acid mixture, and finally add the cooled 0.375g ammonium persulfate and 100mL1mol / L hydrochloric acid Mixed solution, the mixed solution o...

Abstract

The invention provides preparation methods for a MoN nanometer material and a counter electrode. The preparation method for the MoN nanometer material comprises the steps that a hydrothermal method is used for preparing a MoO3 nanoribbon; on the basis of the MnO3 nanoribbon, aniline and ammonium persulfate are added, and a cold bath method is used for preparing MoO3.PANI; annealing treatment is performed on the obtained MoO3.PANI on the NH3 condition to obtain the MoN nanometer material. The preparation method for the counter electrode comprises the steps that the MoN nanometer material and terpilenol are mixed and ultrasonically stirred, conductive glass is coated with the obtained slurry through a scraping method, and annealing treatment is performed on the argon condition to obtain the counter electrode for assembling. The methods successively achieve preparation of the MoN nanometer material and the counter electrode by means of the MoN nanometer material. A dye-sensitized solar cell is high in photoelectric conversion efficiency and suitable for industrial production.

Description

technical field [0001] The invention relates to a method for preparing a nanometer material, in particular to a method for preparing a MoN nanometer material used for a counter electrode of a dye-sensitized solar cell. The invention also relates to a preparation method for the opposite electrode of the dye-sensitized solar cell. Background technique [0002] With the development of society, energy issues have become the focus of general concern in today's society. Solar energy, as a renewable energy source, is not restricted by geographical conditions and has zero pollution, so it has attracted people's attention. A solar cell is a device that converts light energy into electricity. Dye-sensitized solar cells have become a research hotspot of solar cells due to their advantages such as easy fabrication, no pollution to the environment, low energy consumption in the preparation process, little dependence on temperature and incident light angle, and low cost. [0003] In dy...
