The Cover picture shows the current competing scenario between ful
lerenes and TiO
2 as e
lectron-transport materials for perovskite solar cells, highlighting the benefits associated with ful
lerenes. The emerging perovskite solar cell community generally uses TiO
2 as the e
lectron-transport material. However, there are other materials, such as ful
lerenes, deserving to be explored owing to their potential integration by using low-temperature scalab
le processes. More details can be found in the Full Paper by Collavini et al. on
