The Cover picture shows the
current
competing s
cenario between fullerenes and TiO
2 as ele
ctron-transport materials for perovskite solar
cells, highlighting the benefits asso
ciated with fullerenes. The emerging perovskite solar
cell
community generally uses TiO
2 as the ele
ctron-transport material. However, there are other materials, su
ch as fullerenes, deserving to be explored owing to their potential integration by using low-temperature s
calable pro
cesses. More details
can be found in the Full Paper by Collavini et al. on
