Electroplating technical requirements for solar container connectors

Which plating method is not suitable for SHJ solar cell process?

The plating methods applied in diffused-emitter solar cell, such as laser ablating SiNx 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.

Can electroplating improve the quality of Ni seed layer on Topcon SCS?

In this work, we proposed an electroplating method to enhance the quality of the Ni seed layer on TOPCon SCs by lowering the electrodeposition temperature, thereby preserving the contact integrity between the metal grid and the polysilicon layer.

Is copper plating a suitable alternative electrode solution for SHJ solar cell?

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 [, , ].

How did new plating technology improve electroplating?

The development of new plating solutions allowed for the plating of a wider range of metals, including nickel, copper, and zinc. New equipment, such as barrel plating machines and continuous plating lines, improved the efficiency and consistency of the electroplating process .

Is copper plating a good choice for solar cells?

Despite the many challenges, copper plating is still a promising candidate for high efficiency and low cost SHJ solar cells, especially in terms of cell cost as compared with sharply increasing silver price. Jian Yu: Conceptualization, Writing - original draft.

Can copper metallization be applied on SHJ solar cell?

However, the application of the copper metallization on SHJ solar cell is totally different from diffused-emitter solar cell. Some barriers including not cost-effectively process, complicated electroplating steps, long-term degradation and reliability have been identified as the obstacles to its industrialization.
