Researchers from Imperial College London, the University of Cambridge and Soochow University in China found that new green materials currently being developed for next-generation solar panels could also be useful for extracting energy from artificial light. I she studies was published in the Advanced Energy Materials magazine.
The team studied “perovskite-inspired materials” that were developed to get around the problems of perovskites designed for next-generation solar cells. Although the production of perovskites is cheaper than the production of traditional silicon-based solar panels, while still providing similar efficiency, their disadvantage is that they contain toxic lead substances.
This has led to the development of more environmentally friendly perovskite-like materials based on safer elements such as bismuth and antimony. However, they are not as effective at absorbing sunlight. However, the team found that they are much more effective at absorbing light indoors, and their effectiveness holds promise for commercial use.
Scientists have shown that the energy provided by these materials under artificial lighting is sufficient to power electronic circuits. Lead-free materials inspired by perovskite could therefore soon enable the production of battery-free wearable electronic devices or devices for smart homes and smart cities.
