Fused Triphenylamine‐Terminated Self‐Assembled Hole‐Transporting Monolayers for Perovskite Solar Cells
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 an important approach to enhancing device efficien...
