In article number 1807556 , Takeshi Sano, Junji Kido, and co‐workers demonstrate a low‐temperature solution‐processed TFB as an ideal hole‐transporting layer to push the power conversion efficiency of one‐step‐processed CH 3 NH 3 PbI 3 ‐based inverted perovskite solar cells up to 20.2%. Moreover, this device shows good stability, retaining 90% of its original efficiency after storage for 30 days in ambient air.
