Copper-Aluminum Composite and Copper PV Ribbon

Use a defined copper-ribbon baseline to compare conductor structure, resistance, coating, stringing performance and module-level trial results.

What this comparison provides

Conductor structure and geometry comparison: identify metal layers, proportion basis, coating and actual section before planning the module trial.

Decision	copper-aluminum composite PV ribbon	pure copper PV ribbon	Acceptance basis
Layer construction	Aluminum-containing conductor with a defined copper layer and solderable finish	Copper-base conductor with the specified solderable finish	Record the core, layer ratio basis and coating separately.
Cell geometry	Section and stiffness must be assessed with the actual layered construction	Section and stiffness depend on copper grade and condition	Match cell pads, ribbon dimensions and stringer setup; do not assume the same cross-section yields equal resistance.
Joining and reliability	Check the copper surface, cut ends and coating in the cell process	Check the copper grade, coating and cell process	Compare peel method, EL inspection, resistance and module tests using the same bill of materials.
Cost basis	Include qualified composite section, coating and process yield	Include qualified copper section, coating and process yield	Compare cost per accepted module; do not infer saving from price per kilogram.
