Liquid solar cell and preparation method thereof

Abstract

The invention discloses a liquid solar cell having a changeable structure and adjustable photovoltaic effects, and a preparation method thereof. The liquid solar cell comprises a container which comprises a substrate and an enclosing wall, wherein the enclosing wall is composed of sidewalls and a top wall; the enclosing wall is fixed on the substrate to form the container with a sealed structure; the lower surface of the top wall is provided with upper electrodes; the upper surface of the substrate is provided with a lower electrode; the container is filled with ferroelectric liquid; the ferroelectric liquid is composed of ferroelectric nanometer particles, lipophilic surfactants and oily base fluid. The liquid solar cell preparation method comprises the steps of: 1) preparing the upper electrodes and the lower electrode; 2) preparing the container with the upper electrodes and the lower electrode; and 3) preparing the liquid solar cell: mixing the ferroelectric nanometer particles, the lipophilic surfactants and the oily base fluid to obtain ferroelectric liquid, and adding the ferroelectric 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.
