Swedish researchers unlock the secrets of halide perovskite materials with machine learning, creating ultra-thin, efficient, and durable solar cells to power everything from phones to buildings. This technology is set to fast-track a sustainable energy future!

Researchers at Chalmers University of Technology in Sweden have achieved a groundbreaking discovery in renewable energy by unraveling the hidden structure of halide perovskite solar materials, specifically formamidinium lead iodide, through machine learning and advanced simulations. This solves a longstanding mystery about the material's low-temperature phase, enabling the development of more durable and efficient ultra-thin solar cells with applications ranging from mobile phones to entire buildings.
Combining computer simulations with machine learning allowed for simulations thousands of times longer and involving millions of atoms, far beyond previous capabilities of just hundreds. By modeling scenarios like cooling the material to -200°C, the team revealed how formamidinium molecules become trapped in a semi-stable state. These findings were confirmed by lab observations from the University of Birmingham and published in the Journal of the American Chemical Society on August 14, 2025.
This advancement is crucial for optimizing the stability and performance of perovskite solar materials. With global electricity consumption projected to exceed 50% of total energy use in 25 years, ultra-thin solar cells offer environmentally friendly energy conversion solutions to meet this demand. Principal investigator Julia Wiktor stated, "To meet the demand, there is a significant and growing need for new, environmentally friendly and efficient energy conversion methods, such as more efficient solar cells. Our findings are essential to engineer and control one of the most promising solar cell materials for optimal utilization." This breakthrough holds immense potential to revolutionize sustainable energy technologies and integrate ultra-thin solar panels into everyday life.
