More and more crystalline silicon (c-Si) solar cells, which are dominating the photovoltaic (PV)application, will be decommissioned after the service term due to the performance degradation. It willbe valuable if the degraded c-Si solar cells can be recycled for reuse. For this, to restore theperformance of the recycled c-Si solar cell becomes important. Here, we developed a two-step Ag/Cuelectroplating method to repair Ag grid electrodes of the degraded c-Si solar cell. Such repairimproved aspect ratio and excellent conductivity of the repaired Ag/Cu finger electrodes wereobtained. Meanwhile, the absolute efficiency value of the repaired c-Si solar cell had 118%improvement after the Ag/Cu plating repairing process. In addition, the two-step plating Ag/Cuprocess is easy to operate, economic and friendly to the environment. These results demonstrated thatthe two-step electroplating Ag/Cu could be a promising method to repair and reuse the degraded c-Sisolar cells..
