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 …

Multistrategy Preparation of Efficient and Stable Environment-Friendly Lead-Based Perovskite Solar Cells

Perovskite solar cells (PSCs) have achieved huge success in power conversion efficiency (PCE) and stability. However, further improving the PCE of PSCs and stability is still a big challenge. Here, we attempt to improve the PCE and stability of PSCs …

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 …
