Functionalized polymer modified buried interface for enhanced efficiency and stability of perovskite solar cells

Although great progress has been made in perovskite solar cells (PCSs), further development of PCSs is hindered by a large number of defects, nonradiative recombination, and mysterious stresses. Here, we propose a new interfacial strategy by …

Modifying the buried interface with azodicarbonamide for high-efficiency MA-free perovskite solar cells

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 …

Interfacial defect passivation and stress release by multifunctional KPF6 modification for planar perovskite solar cells with enhanced efficiency and stability

Interfacial defect and residual stress hinder the further enhancement of power conversion efficiency (PCE) and stability of perovskite solar cells (PSCs). Here, we report a multifunctional interface modification strategy where KPF6 molecule is …
