Title:
PREPARATION METHOD FOR GRID LINE, PREPARATION METHOD FOR CELL SHEET, AND PHOTOVOLTAIC CELL
Document Type and Number:
WIPO Patent Application WO/2023/232057
Kind Code:
A1
Abstract:
Disclosed in the present invention are a preparation method for a grid line, a preparation method for a cell sheet, and a photovoltaic cell. The preparation method for a grid line comprises the following steps: coating the front face and/or back face of a cell sheet with a mask material, such that the mask material is cured to form a mask; exposing a local area of the mask according to the properties of the mask, so as to form a development reaction area with a width gradient on the mask; and developing the mask in the development reaction area, so as to form a mask opening with a width gradient in the development reaction area; electroplating metal in the mask opening, so as to form a grid line with a width gradient; and removing the mask. By means of the preparation method for a grid line in the embodiments of the present invention, a grid line with a width gradient can be formed on a cell sheet, and after the grid line with a width gradient is packaged into a photovoltaic assembly, the power generation efficiency can be improved.
