Abstract

The invention is applicable in the technical field of photovoltaic cell electroplating, and provides photovoltaic cell horizontal electroplating equipment and method. The photovoltaic cell horizontal electroplating equipment comprises an electroplating bath which is filled with electroplating liquid and is provided with an inlet and an outlet opposite to the inlet, an anode piece which is arranged in the electroplating bath and is located below the liquid level of the electroplating liquid, a cell moving mechanism which is used for driving a cell to move from the inlet to the outlet so as to enable the cell to move relative to the anode piece in the electroplating liquid to realize electroplating, and a cathode conductive assembly; the cathode conductive assembly comprises a rotary moving piece and a plurality of cathode conductive probes arranged on the rotary moving piece, and the rotary moving piece can drive the plurality of cathode conductive probes to synchronously rotate, so that at least one cathode conductive probe makes contact with the cell and keeps synchronous movement with the cell. According to the photovoltaic cell horizontal electroplating equipment, the coating quality of the photovoltaic cell can be effectively improved, and the overall length size of the photovoltaic cell horizontal electroplating equipment can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of photovoltaic cell electroplating, in particular to a photovoltaic cell horizontal electroplating equipment and method. Background technique [0002] With the continuous expansion of the scale of the photovoltaic industry and the rapid development of the market, as well as the adjustment of relevant policies, the market has increasingly strict requirements on the price of photovoltaic cells, resulting in the reduction of complexity in many processes and the use of materials that are easy to obtain. Existing solar cells usually use silver paste printed on the cells, and the silver paste accounts for more than 25% of the total cost of producing solar cells, so how to replace the silver paste is a key point. At present, many companies use electroplating copper to replace printed silver paste. The basic principle is to let the cells pass through the cathode assembly and the anode assembly in turn, and use elec...
