Thus, lower silver paste consumption or substitution of expensive silver paste is of high demand for SHJ solar cell. Copper plating is of great interest and regarded as an ideal alternative electrode solution and industrially proven technology for diffused-emitter solar cell [, , ].
Cu electroplating, as an Ag-free metallization technique, plays an important role in the new metallization technologies of HJT solar cells . This technology has been industrially proven for silicon homojunction solar cells .
The plating methods applied in diffused-emitter solar cell, such as laser ablating SiN x film , light induced plating (LIP) , electroless plating , is not suitable for SHJ solar cell process. The current research progress in electroplating of SHJ solar cells with different methods are summarized in Table 1.
Copper plating is of great current interest to silicon heterojunction application, which has a high potential to cut down the cost and improve cell efficiency by the remarkably reduced shading loss, increased electrode conduction and fill factor.
Conclusion The copper metallization technology for SHJ solar cells needs to break through the complicated process limits before mass production application. This work focuses on some process challenges during copper metallization process on solar cell level and module level.
Silicon heterojunction (SHJ) solar cell has attracted increasing attention for the excellent passivation [, , ], high conversion efficiency over 26.63% and low temperature processing typically below 200 °C . The low temperature silver paste is commonly used for SHJ solar cells.
