Perovskite solar cells could last ten times longer thanks to new research led by the University of Surrey, which suggests alumina (Al₂O₃) nanoparticles significantly enhance the lifespan and stability of these high-efficiency energy devices.
Perovskite solar cells could last ten times longer thanks to new research led by the University of Surrey, which suggests alumina (Al₂O₃) nanoparticles significantly enhance the lifespan and stability of these high-efficiency energy devices.
While perovskite solar cells offer a cost-effective and lightweight alternative to traditional silicon-based technology, their commercial potential has been limited due to a flaw in their structure – primarily caused by iodine leakage. Over time, this escape of iodine can lead to material degradation, reducing performance and durability.
Working in collaboration with the National Physical Laboratory and the University of Sheffield, scientists have now discovered a way to trap iodine by embedding tiny particles of Al₂O₃ – aluminium oxide – within the cell, holding promise for longer-lasting and more affordable next-generation solar panels.
