CN_111490108_A

Resumen de: WO2020155783A1

Disclosed in the present application is a solar cell, comprising a substrate. Two or more cell units arranged at intervals are formed on the substrate, the cell unit comprises at least one electrode assembly, and the electrode assembly comprises multiple grid line electrodes arranged side by side. According to the solution above, grid line electrodes are provided in an electrode assembly and no main grid is provided, thereby significantly reducing the shading area of the solar cell and facilitating improving the photoelectric conversion performance of the solar cell. In the solution, grid line electrodes can be made denser and thinner, and thus, the transmission paths for carriers to the grid line electrodes are greatly shortened, and the series resistance is reduced. In addition, because a main grid is omitted, the silver paste consumption for printing a main grid is saved, and the production cost is reduced. Moreover, because the cell units are arranged at intervals, after cutting the solar cell along the intervals according to needs, there is no silver electrode residue, which occurs when cutting a solar cell having a main grid, at the cutting edges, thereby avoiding the problem of short circuit after interconnection caused by silver electrode residue at the cutting edges.
