In optoelectronics, perovskite materials are particularly attractive due to their excellent absorption, emission, and carrier transport properties, which lead to the improved performance of solar cells, light-emitting diodes (LEDs), lasers, photodetectors, and sensors.
Metal halide perovskite (MHP)-based solar cells and light-emitting diodes (LEDs) have shown a great potential to compete with the conventional optoelectronic devices such as silicon, gallium-arsenide-based inorganic solar cells, and organic LEDs.
When perovskite materials are coupled with plasmonic structures, the device performance significantly improves owing to strong near-field and far-field optical enhancements, as well as the plasmoelectric effect.
