And it might have important ramifications for renewable energy production and achieving zero-carbon goals.
The next-generation cells are predicted to be cheaper, lighter, and more flexible, opening up new uses such as coating glass windows with thin layers of transparent solar panels.
Perovskite's remarkable features were described as "unbelievable, a miraculous material" by Zeev Valy Vardeny, a Distinguished Professor of Physics at the University of Utah, in 2017
Commercialization of the technique was expected to be at least a decade away at the time, but new discovery could hasten that process significantly.
