Reaction‐Time pH Stabilization by Poly(acrylic acid) with Ethanol‐Mediated Growth Control for Efficient Hydrothermal Sb2(S,Se)3 Solar Cells

Advanced Functional Materials, EarlyView.
Poly(acrylic acid) acts as a reaction‐time pH buffer during hydrothermal Sb2(S,Se)3 growth through its COOH/COO‐ equilibrium. When combined with ethanol‐regulated growth, this buffering strategy reduces Sb‐O related surface disorder, improves local electronic uniformity and carrier collection, and increases the champion solar‐cell efficiency to 10.25%,

Insulating‐Passivating Interfaces for Narrow‐Bandgap Tin‐Lead Perovskites Enable High‐Photovoltage in Single‐ and Double‐Junction Solar Cells

Advanced Functional Materials, EarlyView.
Combining field‐effect surface passivation of a narrow‐bandgap tin–lead perovskite by diammonium ions with introducing oleyl‐based amphiphiles to create insulating interface layers between the absorber and the adjacent hole and electron transporting layers increases the open‐circuit voltage to 91.5% of the detailed‐balance limit and enhances the power ...
