Researchers at the University of Queensland (UQ) have unveiled a pioneering advancement in renewable energy with a new eco-friendly solar cell design. Their tin halide perovskite (THP) technology achieved a certified 16.65% efficiency — a nearly 1% improvement over previous THP records — signaling a leap toward affordable, sustainable energy solutions.
The breakthrough, developed in collaboration between UQ's School of Chemical Engineering and the Australian Institute for Bioengineering and Nanotechnology, addresses two critical challenges: reducing reliance on toxic materials and improving production scalability. By replacing lead with safer tin, the team created a solar cell matching the performance of commercial silicon-based alternatives while offering lower costs and greener manufacturing.
"This isn't just incremental progress — it's a game-changer," said Professor Wang Lianzhou, the project's lead. "Our THP cells could revolutionize household solar panels and even power future innovations like electric aircraft."
Key to the advancement was overcoming structural flaws in THP crystalline films. Researcher Chen Peng explained that adding cesium ions stabilized the material, enhancing durability and energy conversion rates. Team member He Dongxu emphasized the environmental benefits: "Tin-based cells eliminate lead pollution risks, making them safer for residential and urban applications."
With global renewable energy demand surging, this innovation positions Australia at the forefront of sustainable tech development. Analysts suggest such advancements could accelerate the transition away from fossil fuels, particularly in sun-rich Asian markets.
