Abstract
The invention provides a mesoporous ball preparing method for solar batteries, including: step A, dissolving n-hexanamine and n-octylamine into absolute alcohol, then adding potassium chloride solution and stirring the solution for three hours; step B, adding titanium isopropoxide and then mixing the solution, and letting the solution standing afterwards; step C, centrifugating the solution to obtain powders, and then washing the powders by ethanol and then baking the powders to obtain a precursor; step D, dissolving the precursor in absolute alcohol under the temperature of 120 degree centigrade for reaction, then washing the product obtained after centrifugation by ethanol, and then roasting the product to obtain medium balls. The medium ball provided by the invention has smooth spherical surface, the sphere diameter is over 1.08 microns, and the photoelectric conversion rate of batteries can be improved while being used in solar batteries.
Description
Technical field
The present invention relates to solar cell, particularly, relate to the mesoporous ball preparation method who is used for solar cell.
Background technology
Mesoporous material is the type material with huge specific surface area and three-dimensional open-framework of a kind of aperture between micropore and macropore.Mesoporous material in the processing of fine chemistry industry, petroleum and natural gas, the field such as adsorb and separate and all be widely used.Because superior performance is arranged, mesoporous material has become the focus of research.Many excellent properties of hole material make it become the focus of investigation of materials.Because this specific character of mesoporous material, make it can absorbing dye be applied to the light anode of solar cell.The pattern of mesoporous material has very big influence to adsorption effect, therefore is necessary to study the good mesoporous ball preparation method of pattern.
Summary of the invention
To defective of the prior art, the purpose of this invention is to provide a kind of mesoporous ball preparation method who is used for solar cell.
According to an aspect of the present invention, a kind of mesoporous ball preparation method who is used for solar cell is provided, comprises the steps:
