A single molecule boosts perovskite solar cell efficiency and lifespan
KAUST ·
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.
