The optoelectronic properties of metal halide perovskite (MHP) semiconductors make them attractive for use as active materials in photovoltaics, LEDs, ionizing radiation detection and photocatalysis. However the practical application of MHPs faces significant barriers. Researchers at The University of Queensland have developed a new class of MHP composites. The precursors can be made from relatively cheap materials, using a scalable mechanochemical process. Similarly, the composite material is fabricated via nearly solvent-free and scalable processing steps.
Key features
- Composite produced using scalable and cost-effective solid-state processing techniques
- Orders of magnitude brighter photoluminescence of composite compared to pure metal halide perovskite
- 10,000 h underwater stability and over two years’ storage stability in air
