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