Abstract

The invention discloses a polycrystalline silicon battery piece, which comprises a main grid and an auxiliary grid, wherein the main grid and the auxiliary grid are connected in a cross shape; a substrate is arranged under the main grid and the auxiliary grid; the substrate comprises a bottom plate, circular grooves and welding grooves; the bottom plate is located under the main grid and the auxiliary grid; the plurality of circular grooves are formed in the upper surface of the bottom plate at equal intervals; the welding groove is formed between every two circular grooves; and the welding grooves are formed in the upper surface of the bottom plate. Compared with the prior art, the polycrystalline silicon battery piece has the following advantages: through cooperation of the polycrystalline silicon battery piece body, the substrate, the main grid and the auxiliary grid, when an operator needs to connect a plurality of polycrystalline silicon battery piece bodies, the polycrystalline silicon battery piece bodies can be placed in the circular grooves, and the polycrystalline silicon battery piece bodies can be straightened and operated, so that the required energy of the operator isreduced, the assembly efficiency is improved, and the situation of poor products is reduced.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a polycrystalline silicon cell. Background technique [0002] The four corners of polycrystalline silicon cells are square corners, and the surface has patterns similar to ice flowers, which are called polycrystalline and colorful in the industry. The panel is a solar module composed of polycrystalline silicon solar cells with high conversion efficiency arranged in different series and parallel arrays. Its function is to convert solar energy into electrical energy. The conversion efficiency of solar cells is generally defined as the output power of the cells and the incident The ratio of the total power of sunlight to the surface of the cell. When sunlight hits the surface of the cell, it will be reflected and refracted. In order to improve the conversion efficiency of the cell, it is necessary to minimize the refraction loss and increase the absorption. Although high-qualit...
