Ion-beam sputtering offers significant benefits in terms of deposition uniformity and pinhole-free thin films without limiting the scalability process. In this work, reactive ion-beam nickel oxide has been developed for hole transporting layer p–i–n perovskite solar cells (PSCs). The process is carried out by oxidation scattered Ni particles with additional post-treatment annealing regimes. Using a rate 1.2 nm/min allowed growth very uniform NiOx coating roughness below 0.5 nm on polished Si...
