In article number 2001073, Hong Meng, Feng Yan, and co‐workers design, synthesize, and successfully use a non‐fullerene electron transport material based on a new spiro derivative, SPS‐4F, in perovskite solar cells, leading to high efficiency as well as good stability of the devices. This work opens a new avenue for developing new spiro‐based electron transport materials and paves a way for realizing high‐performance devices at low costs.
