Scientists in Sweden have cracked a mystery that could transform renewable energy. Their breakthrough explains how a promising solar tech really works. The discovery may unlock thinner and more powerful solar cells for the future.
Global electricity use is rising fast. Experts warn demand could more than double in the next 25 years. Therefore, efficient and sustainable solutions are more urgent than ever.
Researchers at Chalmers University used advanced simulations and machine learning to study halide perovskites. These materials absorb and emit light extremely well. They are also lightweight, flexible, and potentially cheap to produce. However, they degrade quickly, which has limited their use.
One compound, formamidinium lead iodide, shows exceptional potential. Still, its instability created challenges. By uncovering its hidden structure, scientists now understand how to better control and design it.
The team revealed how this material behaves at low temperatures. They discovered that molecules can get trapped in a semi-stable state.
This finding solves a puzzle that puzzled researchers for years.
To confirm the results, the scientists partnered with the University of Birmingham. Together, they cooled the material to –200°C. The tests matched the simulations, proving the theory correct.
Machine learning played a crucial role.
It allowed researchers to run simulations thousands of times longer than before. As a result, the models included millions of atoms, making them closer to real conditions.
These insights provide a roadmap for stronger and more durable solar materials. In addition, they could lead to ultra-thin panels that power everything—from smartphones to skyscrapers. The future of clean energy may have just become brighter.
