In a paper published in nature, the Chinese module maker explained that the 33.9%-efficient tandem device it unveiled in December 2023 is based on a bilayer intertwined passivation strategy that combines efficient electron extraction with further suppression of nonradiative recombination. It also revealed that its two-terminal tandem prototype devices achieved an efficiency of 34.6%.

    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.
