Mie-Resonant Nanoparticles for Light Absorption Improvement of Perovskite Photodetectors

Nowadays various perovskite devices are aimed to generate a new revolution in thin-film electronics. Besides perovskite solar cells and LED, many types of photodiodes are perspective for personal medicine, light control technologies and Internet of Things. This research is dedicated to find new ways of light absorption improvement of perovskite photodiodes in visible and near infrared range where classic narrow band gap-based perovskite devices have poor light sensitivity. There are few new models with improved thickness of perovskite devices improved by Mie-resonant 160 nm Si nanoparticles possess both electric and magnetic multipoles in visible and near IR range which can improve light absorption of thick perovskite photodiodes by 10%.
