Non‐Stoichiometric AlO x– Modified Al‐Doped MoO x Passivating Contacts Enabled High‐Efficiency Dopant‐Free Silicon Solar Cells

ABSTRACT Transition‐metal oxides such as MoO x are attractive hole‐selective contacts for crystalline silicon (c‐Si) photovoltaics; however, their performance is fundamentally limited by oxygen‐vacancy–induced work‐function instability, interfacial Fermi‐level pinning, and insuff...

Triboron Multiresonant Emitter With Zigzag B/N Alignment Enables Near‐Degenerate Singlet–Triplet States for High‐Performance Non‐Sensitized OLEDs With Mild Roll‐Off

ABSTRACT Boron/nitrogen‐embedded polycyclic frameworks are attractive emitters in organic light‐emitting diodes (OLEDs) because they combine narrowband emission with thermally activated delayed fluorescence. Linear extension of multiresonant frameworks with zigzag boron/nitrogen...
