Researchers from Japan have developed organic semiconductors that can both emit light and harvest energy, a significant advancement that could revolutionize smartphones, wearable devices, and sustainable energy solutions.
The team led by Professor Hirohiko Fukagawa from Chiba University used multiple-resonance thermally activated delayed fluorescence (MR-TADF) materials to control exciton binding energy, enabling both efficient light emission and power generation in a single device.
The devices achieved light-emission efficiency exceeding 8.5% and power-conversion efficiency around 0.5%, far surpassing previous attempts and approaching theoretical limits with minimal electrical loss.
The breakthrough opens the door to self-sustaining electronics, including smartphone screens that recharge themselves using ambient light, wearable devices that harvest energy from indoor/outdoor lighting, battery-less sensors for IoT networks, and visible light communication systems that store energy for nighttime use.
This innovation aligns with global efforts to reduce energy consumption and carbon footprints, paving the way for smaller, lighter, and more sustainable devices that operate autonomously by harvesting light.
A groundbreaking scientific achievement has shattered previous limitations in organic semiconductor technology, paving the way for self-powered electronics that could revolutionize smartphones, wearable devices and sustainable energy solutions.
