Composite and Copper PV Ribbon: Plan a Side-by-Side Trial
Use the current copper ribbon as the baseline. Compare conductor structure, resistance, coating and dimensions, then run both materials through the specified stringing process. Record joint quality, cell stress, module results and material use under the same trial conditions.

| Decision | Copper-Aluminum Composite PV Ribbon | Conventional Copper PV Ribbon | Acceptance basis | Your input or result |
|---|---|---|---|---|
| Conductor | Copper-aluminum layered conductor with defined solder coating | Copper-base conductor with defined solder coating | Record layer structure separately from the solder finish. | |
| Trial design | Candidate section and required material quantity | Current production ribbon section and quantity | Hold required resistance, module layout and trial conditions constant. | |
| Process and results | Record joining, cell stress, EL/module results and yield | Record the same joining, cell stress, module results and yield | Use side-by-side results; conductor mass alone does not establish a module gain. |
