Unusual Temperature‐Enhanced Bulk Photovoltaic Effect Beyond the Centrosymmetric Phase in CuCrP2S6 van der Waals Crystals

Advanced Functional Materials, EarlyView.
Contrary to conventional expectations, the bulk photovoltaic effect in CuCrP2S6 is enhanced rather than suppressed upon transitioning into the crystallographically centrosymmetric phase. Dynamic Cu‐ion disorder creates transient polar states, which substantially amplifies zero‐bias photocurrent (shift‐current) generation, establishing dynamic symmetry ...

Intrinsic Interfacial Energy Alignment Enables ETL‐Free Organic Solar Cells

Advanced Functional Materials, EarlyView.
Molecular orientation of the small‐molecule donor BTR‐Cl induces a vacuum‐level shift that pins the Fermi level at ∼4.4 eV at the active layer/Ag interface, enabling Ohmic contact formation without an electron transport layer. This strategy is extended to ternary PM6:Y6:BTR‐Cl devices, achieving an ETL‐free efficiency of 18.6% with enhanced operational
