Sounds like it's still a solar cell though, they just figured out how to make it thinner and flexible. By the time you stack them into a cell, is there really any difference?

"By stacking multiple light-absorbing layers into one solar cell (known as a multi-junction approach), a wider range of the light spectrum is harnessed, allowing more power to be generated from the same amount of sunlight.

This thin-film perovskite material has been independently certified by Japan’s National Institute of Advanced Industrial Science and Technology (AIST) to deliver over 27% energy efficiency. It matches the performance of traditional, single-layer silicon PV for the first time."

Another perovskite hype piece. You'll know that they've got something that's commercially viable once they're making these sorts of efficiency claims and not omitting information about cell degradation.

We could generate solar power before we even had solar panels. You just used the sun to heat up water. Solar panels made solar power generation more effective.

This will bring new meaning to the idea of a burner bag.
