A single molecule boosts perovskite solar cell efficiency and lifespan

Summary

KAUST researchers contributed to an international collaboration demonstrating that an ionic salt molecule called CPMAC enhances perovskite solar cell performance by 0.6%. CPMAC improves the electronic properties and reduces defects in the electron transfer layer compared to C60. CPMAC solar cells also exhibited greater stability, with a one-third reduction in power conversion efficiency drop compared to C60 cells under heat and humidity. Why it matters: This advancement addresses a key limitation in perovskite solar cell stability, potentially leading to more efficient and durable renewable energy solutions.
