The copper electroplating process of heterojunction solar cells mainly includes four major process links: seed layer preparation, patterning, metallization (electroplating), and post-processing. The processes of each link are complex, there are multiple technical routes, and the equipment principles vary greatly.
Progress in Photovoltaics: Research and Applications
For IBC solar cells, the subsequent plating step will close the trench to some extent, which advocates the use of not too narrow trenches to avoid short circuiting. The electrical contact separation of the depicted structures in Figure 3 B was demonstrated, although few aluminum residuals are visible in the trenches.

What is Electroplating? Process, Types, and Benefits
Electroplating Working Principle. The working principle of the electroplating process is based on the electrolysis mechanism. It says that passing current on an aqueous solution causes a non-spontaneous chemical reaction, where ions in the solution move toward electrodes. As a result, oxidation occurs at the anode. Here, how …

This paper reports on the evolution of metal plating techniques, from their use in early silicon solar cells, to current light-induced plating processes. Unlike screen-printed metallisation, metal plating typically requires an initial patterning step to create openings in a masking layer for the subsequent self-aligned metallisation.
Electroplating. Many decorative objects, like jewelry, are manufactured with the aid of an electrolytic process. Electroplating is a process in which a metal ion is reduced in an electrolytic cell and the solid metal is deposited onto a surface. The figure below shows a cell in which copper metal is to be plated onto a second metal.
