Liquid solar cell and preparation method thereof

Abstract

The invention discloses a liquid solar cell with variable structure and adjustable photovoltaic effect and a preparation method of the liquid solar cell. The liquid solar cell comprises a container, wherein the container comprises a substrate and a surrounding wall; the surrounding wall is composed of a side wall and a top wall; the surrounding wall is fixed on the substrate to form the container; an upper electrode is arranged on the lower surface of the top wall; a lower electrode is arranged on the upper surface of the substrate; the container is filled with magnetoelectric liquid; the magnetoelectric liquid is prepared by mixing core-shell structure nanoparticles, a hydrophilic surfactant and oily base liquid; the cores of the core-shell structure nanoparticles are magnetic particles; and the claddings are ferroelectric particles. The preparation method of the liquid solar cell comprises the following steps: (1) preparing the upper electrode and the lower electrode; (2) preparing the container; and (3) adding the magnetoelectric liquid to the container to obtain the liquid solar cell.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a liquid solar cell and a preparation method thereof. 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 relati...

Problems solved by technology

Regardless of the method, it is difficult to obtain nanowires with a specific orientation, and the preparation process is relatively complicated

[0005] In addition, there are some defects in making nanowires into solar cells. For example, because the nanowires are relatively thin, how to connect the electrodes to the nanowires to transmit photo-generated carriers is more troublesome; second, if the nanowires are broken due to some reasons If it is dropped, the entire solar cell will be scrapped, and it must be remade, which is time-consuming and laborious; Third, once the nanowire solar cell is completed, the shape and structure cannot be changed, and the photovoltaic effect cannot be controlled.
