"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."

How does that make them suitable for commercial use?

I believe my solar panels are guaranteed to be at 90 percent of their initial performance after 25 years, for comparison.
Thats super low honestly. Assuming 8 hours per day on a yearly average that's just 75 days. I actually don't know how many hours a panel is operational per day on average. But even putting in 3 hour, which seems obscenely low, it's a remarkably short life.

In fact I'm worried these will just turn it heaps of trash. At least traditional PV have a long lifespan.

Short lived, cheap, and toxic. Not a great combination.
Your comment may be a true reflection of The Independent,

But on review of the Nature article https://www.nature.com/articles/s41467-023-37492-y that that rag ripped and misquoted from I find

The encapsulated devices maintained 100% of their initial performance after 600 hours of operation at maximum power point in ambient conditions

You will find relevant facts and figures in peer reviewed articles. The article states that perovskite is a promising material dependant on resistance to oxygen and to the material substrate.
