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."
Wow though - 27% is no small feat
For sure. Coat buildings with this and we all win
And if they coat the insides too we’ll have free energy forever!
