New approach improving stability and optical properties of perovskite films

(City University of Hong Kong) Metal halide perovskites are regarded as next generation materials for light emitting devices. A recent joint-research co-led by the scientist from City University of Hong Kong (CityU) has developed a new and efficient fabrication approach to produce all-inorganic perovskite films with better optical properties and stability, enabling the development of high colour-purity and low-cost perovskite light-emitting devices (LEDs) with a high operational lifetime.
