A series of metal acetylacetonates produced by a full low‐temperature (below 100 °C) process are successfully employed to obtain both “multistable” and high‐performance planar‐inverted perovskite solar cells. All the three kinds of champion cells in small area exhibit over 18% in conversion‐efficiency with negligible hysteresis, along with a conversion efficiency above 16% for planar PSCs in an aperture area of over 1 cm 2 .
