Efficiency records involving perovskites are generally not that interesting without any longevity data. As far as I'm aware, the lifetime of current SotA perovskite solar cells is measured in weeks or months. That's not commercially viable.

Not that efficiency research is completely useless, but the longevity is the real challenge that's holding this up.

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

By adapting the formulation and synthesis of the perovskite and the cell design and encapsulation optimization, Oxford PV succeeded in mitigating stability-related deficits and aims at providing future buyers of their modules with the industry-standard 25 year performance 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.
