Longi achieves 34.6% efficiency for two-terminal tandem perovskite solar cell prototype

This is a most excellent place for technology news and articles.
I think it's still interesting as it shows the potential.
And Oxford PV recently had a commercial sale of a perovskite solar panel with a 25 year guarantee
Interesting. Cost is also very important for large scale deployment of course. I wonder if this stuff can become competitive in $ per watt with the current silicon cells.
I've seen them say their solar panels will provide more energy for the same amount of land at a lower cost.
But it doesn't seem like their prices are publicly available yet.
