Electrophilic Molecule-Induced π-π Interactions Reduce Energy Disorder of Hole Transport Layer for Highly Efficient Perovskite Solar Modules

The Poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine (PTAA) is commonly used as a co-hole transport layer in inverted perovskite solar cells (PSCs). It can effectively improve the hole transport capability of NiOx and obstruct interfacial...
