Asymmetric Lamellar Templating of the Perovskite/C60 Interface for Scalable Inverted Perovskite Photovoltaics

Advanced Materials, EarlyView.
Asymmetric lamellar templating at the perovskite/C60 interface is achieved using a laterally polarized indole spacer. Surface anchoring and Ind–Ind assembly form a π‐rich lamellar interphase that supports uniform C60 contact formation, suppresses recombination, preserves electron extraction, and enables certified high‐efficiency cells and modules with ...

Direct Growth of 2D Bilayers on Au(111) for Low‐Coercive Sliding Ferroelectricity

Advanced Materials, EarlyView.
Controlled CVD growth of stacking‐defined bilayer ReS2 on Au(111) enables parallel‐stacked bilayers with intrinsic sliding ferroelectricity, a strong piezoelectric response, and an ultralow coercive voltage. Atomic‐resolution imaging and in situ measurements further reveal the decisive role of clean interfaces in achieving low‐barrier ferroelectric ...
