6 FAQs about [Solar cell plating phenomenon]
What is a Ni/Cu based plating technique for silicon solar cells?
This paper offers a detailed review and understanding of a Ni/Cu based plating technique for silicon solar cells. The formation of a Ni seed layer by adopting various deposition techniques and a Cu conducting layer using a light induced plating (LIP) process are appraised.
How to plat a solar cell?
The plating step can be done either with the irradiation of the front side of the cell by LIP in case of p- type cells or without light irradiation (FBP forward bias plating) in case of n-type solar cells for single sided processing. 92 G. Cimiotti et al. / Energy Procedia 67 ( 2015 ) 84 – 92 6.
Can metal plating be used to metallise silicon solar cells?
Increasing silver prices and reducing silicon wafer thicknesses provide incentives for silicon solar cell manufacturing to develop new metallisation strategies that do not rely on screen printing and preferably reduce silver usage. Recently, metal plating has re-emerged as a metallisation process that may address these future requirements.
What is plated metallization process for silicon heterojunction solar cells?
We introduce a new plated metallization process for Silicon Heterojunction (SHJ) solar cells by selective plating of copper onto a positively masking seed layer. This process tackles the issues of high silver consumption and low grid conductivity of screen printed contacts on SHJ solar cells.
Is nickel/copper based metal plating a metallization method for silicon solar cells?

How does copper plating work on SHJ solar cells?
Theoretical approach Copper plating on SHJ solar cells results in the coverage of the entire surface with plated metal due to the conductive ITO layer which is exposed to the electrolyte bath. However, the Cu plating rate on a metal oxide layer is lower than on a pure metal surface owing to their different electrochemical behavior.
