So is part of the bet here that future potential efficiency numbers will continue to increase at a rate faster than silicon can? Or is strictly a low cost play?

- ResearchAtPlay 6y agoEfficiency improvements amplify cost reduction per kWh electricity: An ever growing share of PV system costs stems from every item that is not a a module (inverter, cables, labour etc). Modules are becoming cheaper faster than other components, so reducing module costs further has diminishing returns. In contrast, taking your module efficiency from 20% to 21% increases electricity generation by 5% and thus reduces costs per kWh by 5%.
