New Ionic Liquid Breaks Stability Barrier for Perovskite Solar Cells
A new ionic liquid additive developed by researchers at Purdue and Emory universities could transform perovskite solar technology. The compound stabilises crystal growth and buried interfaces, dramatically slowing heat- and light-driven degradation. Solar cells treated with the additive retained about 90% of their efficiency after 1,500 hours at 90°C, outperforming previous records. The approach is compatible with scalable manufacturing, bringing durable, low-cost perovskite photovoltaics closer to real-world use.
