A new, all room‐temperature solution process is developed to fabricate efficient , low‐cost, and stable perovskite solar cells (PVSCs). The PVSCs show high efficiency of 17.10% and 14.19%, with no hysteresis on rigid and flexible substrates, respectively, which are the best efficiencies reported to date for PVSCs fabricated by room‐temperature solution‐processed techniques. The flexible PVSCs show a remarkable power‐per‐weight of 23.26 W g −1 .
