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...
