Preparation method of nanochain solar cell

Abstract

The invention discloses a specifically-orientated nanochain solar cell preparation method. The method comprises a first step of preparing electrodes in which a substrate and a surrounding wall are taken, the surrounding wall comprises a side wall and a top wall, a lower electrode is prepared on the upper end surface of the substrate, and an upper electrode is prepared on the lower surface of the top wall, a second step of preparing a container in which the surrounding wall is fixed on the substrate and a container with a sealed structure is obtained, a third step of preparing a magnetoelectric colloid in which magnetic nano particles and ferroelectric sol are prepared, the magnetic nano particles are added to the ferroelectric sol for uniform mixing, a magnetoelectric colloid is obtained, and the magnetoelectric colloid is added to the container, and a fourth step of preparing a nanochain solar cell in which a magnetic field is applied to the container, a magnetic nanochain along the magnetic field direction is obtained, the container is baked while the magnetic field is applied until the magnetoelectric colloid in the container becomes gel, the container is then burnt, and after the surrounding wall of the container is burnt or decomposed, a nanochain solar cell is obtained.

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...
