Fused Triphenylamine‐Terminated Self‐Assembled Hole‐Transporting Monolayers for Perovskite Solar Cells

ABSTRACT Conventional self‐assembled hole‐transporting monolayers (SAMs) in perovskite solar cells (PSCs) suffer molecular aggregation, uneven coverage on rough FTO substrates, and insufficient interfacial defect passivation. The design and application of novel SAMs have become a...

Identifying ion and carrier behavior in perovskite solar cells through impedance spectra

Abstract Due to the interference of ion dynamics in perovskite materials, specifically the mixed ionic-electronic conduction property, the impedance response of perovskite solar cells exhibits numerous anomalous features. Herein, we conduct numerical simulations using the drift-d...
