Method for horizontally electrochemically depositing metal

A method for horizontally electrochemically depositing metal on the cathode surface of a crystalline silicon solar cell, comprising the steps of

• disposing the upper metal anode above the upper cathode surface of the crystalline silicon solar cell being prepared for the metal electrochemical deposition process;
• or
• enabling the electrolyte solution to contact the upper metal anode and continuously flow down to the upper cathode surface the crystalline silicon solar cell being prepared for the metal electrochemical deposition process;
• after the lower metal anode is soaked in the electrolyte solution, the electrolyte solution contacts the lower cathode surface of the crystalline silicon solar cell being prepared for the metal electrochemical deposition process;
• or
• after the electrolyte solution contacts the lower metal anode, the electrolyte solution is continuously sprayed upwards to the lower cathode surface of the crystalline silicon solar cell being prepared for the metal electrochemical deposition process.
