The diameter is the catch. On an interconnect ribbon the extra width sits in front of the cell and shades it, which takes back part of the gain. Three further questions have to be answered before copper-clad aluminium is a drop-in replacement: how strong and how stable the copper-aluminium interface is, because thermal cycling that cracks it raises resistance; what happens at a cut end, where the aluminium core is exposed to damp heat and forms a copper-aluminium galvanic couple; and how the lower strength and fatigue resistance of aluminium behave as the section gets finer. On the evidence so far, busbar ribbon is the easier entry point, since it is not size-critical and shades nothing. Interconnect ribbon needs the power, reliability and cost arithmetic done properly.

Thinner and finer ribbon. Reducing the section cuts copper directly and it is the same direction as the move to finer round wire. The limit is resistance loss, which is set by the cell's gridline design.

Low-silver or silver-free coatings. Silver is a small share of the coating and a real cost when the silver price is high. Replacing SnPbAg with SnPb where the reliability requirement allows is a straightforward saving.
