Washington: Scientists have discovered a new material for next-generation smart windows that not only darken automatically when the Sun is too bright but also convert solar energy into electricity.
Researchers at the Lawrence Berkeley National Laboratory (Berkeley Lab) in the US found a form of perovskite that works well as a stable and photoactive semiconductor material that can reversibly switch between transparent and non-transparent state, without degrading its electronic properties.
The scientists made the discovery while investigating the phase transition of the material, an inorganic perovskite.
