What is the highest efficiency cell used in production plants today? Is that different than used by homeowners?
Edit: I mean widespread usage. One lone 10kw plant using 30% panels was not my intention.
- Schroedingersat 4y agoI believe around 22% is standard for PERC which is dominant. TOPCON and HJT are a smidge over 25% but are a bit more expensive for now and use more silicon and silver. Single junction caps out around 28% at the module level so surpassing this at scale requires commercialising a new technology like these perovskite tandem cells. The other benefit is it reduces consumption of the main limiting critical mineral of silver down to insignificant levels by increasing the voltage on the metal layer.
