Dynamic nanodomains in perovskites reveal potential for better, longer-lasting solar cells.

A landmark study in Nature Nanotechnology has made significant discoveries about small-scale structures known as dynamic nanodomains that have the potential to revolutionize solar energy technology. Scientists at the Department of Chemical Engineering and Biotechnology (CEB) have found how these microscopic structures in lead halide perovskites, a high-potential material for solar cells, can help boost both efficiency and stability.

Lead halide perovskites are at the forefront of solar cell technology because they can convert light into electricity more efficiently. However their potential has previously been restricted by the unstable actions of nanodomains within the material. This new study, by Milos Dubajic and Professor Sam Stranks from CEB, demonstrates how these small structures influence how electrons flow when energized by light.

By understanding and controlling these dynamic nanodomains, researchers can customize perovskites so solar cells are more efficient and durable. This discovery will enable the creation of more efficient and durable solar panels that will accelerate the world's use of renewable energy.

The research was a collaboration of scientists from Imperial College London, UNSW Sydney, Colorado State University, and leading synchrotron centers in Australia, the UK, and Germany. Together, their work is making it possible to crack the codes of how nanotechnology can enhance solar power materials.

"Our findings bring us closer to being able to control the nanoscale characteristics of perovskites, which is the key to record-breaking energy conversion efficiency," said Professor Sam Stranks.

This research marks an important step toward the development of renewable energy solutions, utilizing advanced nanotechnology to help alleviate worldwide issues in solar energy.
