This enabled the growth of larger perovskite crystals inside the oxide scaffold with significantly suppressed non-radiative recombination and improving device performance. This work exemplifies potential applications of such nanoarchitectonic approaches in perovskite opto-electronic devices.encarbon electrodeInkjet printingnanostructurePerovskite solar cellsPhotovoltaicsPhotovoltaikPerowskit- und Organische PhotovoltaikPerowskitsolarzellen und -modulejournal article
