Cover Story Zhu and co-workers demonstrate a type of ultrathin flexible perovskite solar cells based on a 3-μm-thick parylene-C substrate via a flip-over transferring process. The Zr, Ti and Ga-doped indium oxide film is used as the bottom transparent electrode of ultrathin inverted FPSCs, and a remarkable power conversion efficiency (PCE) of 20.2% is achieved. Strikingly, a state-of-the-art power-per-weight of 30.3 W g⁻¹ is realized attributed to both high PCEs and ultrathin-ultralight substrates, demonstrating the great promise of fabricating efficient, ultrathin and ultralight solar cells with parylene-C films (see the article on page 2319).
