Although perovskite solar cells have achieved huge progress, there is still unprecedented room for improvement since there exist non-radiative recombinations at the interface. Herein, we employed azodicarbonamide to modify the buried interface for …
Bulk and interfacial nonradiative recombination hinder the further enhancement of the power conversion efficiency (PCE) and stability of SnO2-based planar perovskite solar cells (PSCs). To date, it is still a huge challenge to minimize the bulk and …
