Abstract

The invention relates to a device for manufacturing a solar cell electrode, which comprises a vision alignment mechanical hand and a rotatable positioning device, wherein the rotatable positioning device comprises a tray, an on-line printing device, a wiring device, an infrared welding device, a cooling device, a bus bar welding device and a wire shearing device; the vision alignment mechanical hand is used for putting a basic solar cell on the tray or taking the basic solar cell down from the tray; and the rotatable positioning device is used for delivering the basic solar cell on the tray to the on-line printing device, the wiring device, the infrared welding device, the cooling device, the bus bar welding device and the wire shearing device. The invention also relates to a method for manufacturing the solar cell electrode. The invention has the advantages that: due to the adoption of a method for welding a conductive grid line and a bus bar on the solar cell, the series resistance is effectively reduced under the condition that the shading area is not increased, and the photoelectric conversion efficiency of the cell is improved.

Description

technical field [0001] The invention relates to a method and device for making solar cell electrodes, in particular to a method for welding conductive grid lines and busbars on crystalline silicon solar cells.
