Skewering buckyballs in a string may secure their position and reduce their movements including aggregations which are potentially problematic for conventional fullerene molecules such as PCBM. Congratulation to Nanjing University research team on reporting that polymeric fullerene PFBS-12 performs better than PCBM for inverted perovskite solar cell in terms of both efficiency and stability. For more information, please check the technical data sheet below and reference cited herein.
