First Solar’s new world record for solar cell efficiency and why it’s important
- lutusp 14y agoLet's not forget that the most important number in solar cell technology is, not maximum cell efficiency, but watts per dollar expended on installed capacity (i.e. W/$). Measured that way, competing technologies shake out differently, and the most efficient cells aren't necessarily in the running. But for the future, as the most promising technologies gain an advantage because of volume production, the relationship changes and the most efficient cells may become contenders in the more fundamental W/$ competition.
