Description

A kind of preparation method of DSSC slurry
Technical field
The invention belongs to area of solar cell, be specifically related to a kind of preparation method of DSSC slurry.
Background technology
DSSC is simple because of manufacture craft, and relative low price probably becomes the leading of following solar cell.
Development along with DSSC, requirement to its material therefor and technology also further improves, preparing high performance DSSC slurry is the key that improves battery efficiency, and simplifying simultaneously preparation technology also is the important prerequisite that reduces cost and move towards industrialization.At present, the preparation technology of DSSC slurry is a bit loaded down with trivial details, effect neither be very good, generally before this about 80 ℃ and under the magnetic agitation, ethyl cellulose is dissolved in the saturating alcohol of turpentine oil, and then to its adding powder (or powder mixed liquor), rolling again after rough the stirring, this technique expense material of not only wasting time and energy, and the DSSC slurry that obtains at last is not too evenly (yet can stay the size particles of reuniting in various degree after the rolling) relatively, the slurry viscosity fluctuation is relatively large, and effect is not so good.
Summary of the invention
The present invention is directed to above deficiency, a kind of preparation method of DSSC slurry is provided.
In order to reach above-mentioned technical purpose, the technical solution used in the present invention may further comprise the steps:
1) at normal temperatures ethyl cellulose is joined in the alcohol then magnetic agitation dissolving, the alcoholic solution of formation ethyl cellulose;

4) with repeatedly Ultrasonic Pulverization dispersion of mixed slurry B, make the granularity of the solid particle among the mixed slurry B below micron order;
5) the mixed slurry B after the Ultrasonic Pulverization dispersion is warming up to 35-40 ℃, revolves steaming and eliminate alcohol, then be warmed up to again 55-70 ℃ and revolve steaming adjusting slurry viscosity to necessary requirement, namely make the DSSC slurry.
The concentration of ethyl cellulose is 0.05g/mL in the alcoholic solution of described ethyl cellulose.
Because the solid bulky grain of reunion is arranged among the ultrasonic front mixed slurry B of the present invention, through after repeatedly ultrasonic, the solid bulky grain of reuniting is ground into below the micron order, and be dispersed among the mixed slurry B, mixed slurry B steams homogenizing through overwinding again, so the slurry that obtains does not at last need rolling, the DSSC slurry that makes is even, homogeneous grain diameter.In addition, the present invention can also recently determine to preset by the quality of adjusting raw material solid content and the viscosity of DSSC slurry.
The present invention is in order to regulate DSSC slurry uniformity and viscosity, and at first mixed slurry B is warming up to 35-40 ℃, revolves to steam to eliminate alcohol, then is raised to 55-70 ℃ again and revolves steaming adjusting slurry viscosity to preset value.Mixed slurry B of the present invention is when revolving steaming for 55-70 ℃, and each component of the organic carrier among the mixed slurry B is fully dissolved each other gradually, thereby reaches the purpose of regulating slurry viscosity.
