> The perovskite solar cells (PSCs) are capable of retaining over 90 per cent of their initial performance after 600 hours of continuous operation

600 hours, so like 25 days? That doesn't sound like a very high bar. How does it compare to the current generation of cells?

As I understand it, continuous running means actually putting (fake) sunlight on the panel continuously for 600 hours. This is done as rapid aging test. A quick google tought me this is within range of commercial cells. As they say in the article, if I might quote fully; "The perovskite solar cells (PSCs) are capable of retaining over 90 per cent of their initial performance after 600 hours of continuous operation, the team noted, making them suitable for commercial use."

> Next-generation perovskite solar panels are 50 per cent cheaper and 50 per cent more efficient than traditional silicon cells
