[0038] Step 1) Preparation of electrodes

[0039] Taking the pulsed laser deposition method as an example, other methods such as magnetron sputtering, sol-gel method, etc. may also be used. to La 0.7 Sr 0.3 MnO 3 As the lower electrode as an example, other materials can also be used, such as conductive oxide ITO, La 0.5 Sr 0.5 CoO 3 etc. Or Metal, Au, Pt, Ag etc. First in SrTiO 3 Substrates (of course, other types of substrates, silicon wafers, glass, etc.) are ultrasonically cleaned in acetone and alcohol, and dried; the substrate table is polished with sandpaper, and cleaned, and the dried The substrate is glued on the substrate stage with thermally conductive silver, and then the substrate is blocked with a corresponding mask according to the shape, size and number of electrodes required. After drying, put it in the cavity on the heating table and start vacuuming. Wait until the air pressure reaches 10 -4 Pa, start heating the substrate stage. Note that it should...

Abstract

The invention discloses a preparation method of a nanometer chain solar battery with a specific orientation. The method is carried out according to the following steps: step one, preparing electrodes, i.e., taking a substrate and an enclosing wall which includes a side wall and a top wall, preparing a lower electrode at the upper end surface of the substrate, and preparing an upper electrode at the lower surface of the top wall; step two, preparing a container, i.e., fixing the enclosing wall on the substrate to obtain the container; step three, preparing a magnetoelectric liquid, i.e., taking a magnetic-electric core-shell structured nanometer particles, a lipophilic surfactant and an oil base fluid, uniformly mixing the magnetic-electric core-shell structured nanometer particles, the lipophilic surfactant and the oil base fluid to obtain the magnetoelectric liquid, and adding the magnetoelectric liquid into the container; and step four, preparing the nanometer chain solar battery, i.e., applying an electric field to the container to obtain a ferroelectric nanometer chain, braking the container while the magnetic field is applied, after the oil base liquid and the lipophilic surfactant are dried, calcining the container, and obtaining the nanometer chain solar battery after the enclosing wall of the container is combusted / decomposed.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a preparation method of nano chain solar cells. Background technique [0002] The energy crisis is a major problem faced by countries all over the world, and the development of renewable energy is an effective way to alleviate this problem. Among many renewable energy sources, solar energy is favored because of its advantages such as abundant resources, wide distribution, and cleanliness. Photovoltaic power generation is a major form of solar energy development. Its principle is to use the photovoltaic effect to make photovoltaic cells to convert the sun's light energy into electrical energy. Photovoltaic cells are mainly divided into silicon, copper indium selenide, gallium arsenide, cadmium telluride and polymer photovoltaic cells. Thin-film solar cells produced in the existing industry have disadvantages such as low conversion efficiency, poor stability, and relatively h...
