It was rhetorical cause you obviously don't. But you are arguing for the slower, more expensive option. Current panels are faster and cheaper. The efficiency doesn't really matter for utility solar.

It is unlikely that perovskite panels will ever get cheap enough for efficiency gain to matter unless there is some breakthrough in production. Current solar panels have too much of a head start.

> But you are arguing for the slower, more expensive option

No I'm not. I'm not arguing for anything. I'm excited to have more options for solar deployments! If the best option for a current time & deployment is silicon, then great! Use silicon! If perovskite does nothing more than put price pressure on silicon to get even cheaper, then that's great, too! I'm excited about green technologies :)

We'll see! We're pretty good at making improvements. Will perovskite see the same amazing price drop that silicon has? I don't know, but I'm excited to see the first step in that possible path happening.

Solar panels will continues to be installed at a breakneck pace for likely another decade or more. So the sooner we get more efficient panels, the sooner they can be installed rather then the less efficient ones. It's very straight forward what they were saying.

This thread has been a wild exercise in people tripping all over their own feet in their huge rush to educate me that a new technology is not some flawless miracle device, lol.
