In article number 1500038, Baoquan Sun and co‐workers report the development of a novel sandwiched structure of TiOx/gold nanoparticles (Au NPs)/TiOx to remedy the trap states in low‐temperature‐processed TiOx films. Hot carriers are injected from Au NPs to the TiOx film and reduce the trap states under solar illumination; this results in a champion perovskite solar cell with the power conversion efficiency of 16.2%.
