Sedimentation.No matter which kind of method, is all difficult to obtain the nano wire with specific orientation, and preparation process is more complicated.
In addition, nano wire is made into solar cell in the presence of some defects, such as because nano wire is thinner, how by electricity
It is cumbersome thing that pole connects transmission photo-generated carrier with nano wire；If second, nano wire is for some reason
Break, whole solar cell is just scrapped, it is necessary to make a sample again, waste time and energy；Thirdly, nanowire solar cells one
Denier is carried out, and shape, structure are all unmodifiable, and photovoltaic effect also can not just regulate and control.
The content of the invention

The involucrum of structure nanoparticle is ferroelectricity particulate.
The ferroelectricity solar cell studied at present is all solid-state, and the ferroelectricity solar cell of liquid has not been reported.This is
Because when ferroelectric material is in liquefaction, temperature is typically all higher than its ferroelectrie Curie temperature, and now ferroelectric material has been
Through losing ferroelectricity.Therefore, we propose " liquid solar energy battery " this concept first in the world, and give its system
Preparation Method.
But, so-called liquid solar energy battery here, does not mean that proper " liquid " solar-electricity
Pond (temperature that material is in liquid is all higher than its Curie temperature, so there is presently no the ferroelectric substance of liquid), and refer to

Sub (Charge repulsion) or the colloidal dispersion that long-chain molecule (repulsion of position power) reaches anti-agglomeration and forms stabilization is taken on surface, it
Magnetic field is applied to particulate afterwards so that particulate turns into chain, is connected with electrode with nano wire, just constitutes solar cell.
By adopting the above-described technical solution, the present invention has the advantages that：
1st, ferromagnetic fine particles have flowable, and its form is unbodied, therefore, liquid solar energy battery structure is variable,
Photovoltaic effect controllable, using in extensive range.
2nd, under magnetic fields, it can be rotated with ferroelectric particulate, and due in a liquid, so it is rectified
Stupid field can be smaller, and due to Brownian movement, the steering under magnetic field is easier.Need to apply relatively large electric field in solids
Change polarised direction could be allowed, it is breakdown that electric field easily causes greatly very much sample.
3rd, under electric field action, the orientation of electricdomain can only take along close to some of direction of an electric field in solid-state ferroelectric material
To might not be along direction of an electric field, and for ferroelectricity liquid, because ferromagnetic fine particles can freely turn in a liquid
It is dynamic, therefore the orientation of its electricdomain can be completely along magnetic direction.
