Nanoscale amorphization of poly(triarylamine) for efficient and stable inverted perovskite photovoltaics
{{output}}
Perovskite solar modules require hole-selective layers that combine efficient charge extraction, interfacial uniformity and scalable processing. Poly(triarylamine) (PTAA) is widely used in high-performance inverted perovskite photovoltaics, but its nanoscale c... ...
