2nd step：High-temperature baking is put into by structure is obtained in previous step, it is therefore an objective to falls the substance decomposition of the roof of leg. As for the material of leg side wall different materials can be selected to decide whether to decompose as needed, concrete condition is as follows：If The pattern from side measurement nano chain is needed, then needs to fall sidewall decomposition, otherwise bad observation.Measurement surface pattern when Wait, if Sidewall Height is more than the height of Top electrode, so that when bad observation surface topography, it is necessary to by sidewall decomposition Fall.If the property of measurement vertical direction nano chain, such as electric conductivity, ferroelectricity etc., at this moment side wall will not cause shadow Ring, then can not have to remove.The last solar battery structure being made up of ferroelectric nano chain for just obtaining Fig. 4.
After nano chain is formed, due to reuniting, cluster-shaped, rather than one one piece point are readily formed between nano chain Open, the factor such as the concentration of reunion degree and particulate, the size for applying magnetic field and time is relevant, vertical as shown in Fig. 3, Fig. 4 To nano chain, since being applied magnetic field, nano chain can just contact with upper/lower electrode, in the case where keeping magnetic field by liquid evaporation it Afterwards, nano chain substantially can also keep original shape, keep contacting with upper/lower electrode.
Obtained solar cell is detected, it is as a result as follows：
As can be known from Fig. 5, the BTO powder prepared by us is substantially spherically-shaped, and average is directly about 20nm.Can from Fig. 6 Know, the I-V curve that is obtained under positive back bias voltage is asymmetric, and this is different mainly due to upper/lower electrode, cause BFO and upper/lower electrode it Between caused by the barrier height difference that is formed.
Furthermore, it is possible to find that the solar cell that we obtain has obvious photovoltaic effect, i.e., under illumination and not illumination, The electric current obtained under identical voltage has obvious difference.Our sample of surface has obvious photovoltaic performance.
The present invention is not limited solely to above-described embodiment, in actual fabrication process, can also turn 90 degrees device, then Apply horizontal magnetic field, first generate horizontal nano chain.After high-temperature baking, after liquid evaporation, due to Action of Gravity Field, nanometer Chain can deposit to bottom, after consolidating, then device be gone to original position, that is, the vertical direction nano chain obtained.
In the present embodiment, Top electrode can not also be prepared on the roof of leg, directly in nano chain during last Upper grown Top electrode.
The present invention is not limited solely to above-described embodiment, if directly generating horizontal nano chain, after high-temperature baking, After liquid evaporation, due to Action of Gravity Field, nano chain can deposit to bottom.This when electrode and nano chain between can produce it is big The space of section.Therefore, if the nano chain of generation transverse direction, Top electrode need not be prepared on the roof of leg, in last mistake Top electrode directly is grown in horizontal nano chain in journey, to ensure Top electrode contact nanometer chain.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical Cross above preferred embodiment the present invention is described in detail, it is to be understood by those skilled in the art that can be Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
