Positional Isomer Engineering for Crystallization Kinetics Control in Wide‐Bandgap Perovskite Solar Cells

Carbon Energy, EarlyView.
Based on the ortho‐para configuration of the amino‐sulfonic acid group, 2,4‐diaminobenzenesulfonic acid (2,4‐DABSA) forms the strongest coordination with the perovskite precursor among its isomers, guiding a unique “fast nucleation followed by slow crystallization” kinetics.

The Role of Current Mismatch on Reverse‐Bias Stability of Monolithic Perovskite/Silicon Tandem Solar Cells

EcoEnergy, EarlyView.
Reverse‐bias stability in monolithic perovskite/silicon tandem solar cells requires a silicon–current‐limited regime. When the perovskite current exceeds the silicon current, the reverse voltage is mainly borne by the silicon cell, reducing perovskite stress.

Modulating Perovskite Crystallization via Multisite Bonding for Enhanced Solar Cell Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study proposes an innovative multisite bonding strategy to regulate crystallization. By employing bidentate ligands N,N‐diethyl‐1,2‐ethanediamine dihydrochloride (DED) that coordinate with uncoordinated Pb2+ and I− vacancies, while simultaneously forming hydrogen bonds with FA+ ions, this synergistic interaction prolongs the perovskite ...

Organotrifluoroborate‐Driven Phase Stabilization and Defect Suppression for Wide‐Bandgap Perovskites

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A multifunctional additive, trifluoro(pyrrolidin‐1‐ium‐1‐ylmethyl) borate (PyMe‐BF3), leverages B‐F coordination and N‐H hydrogen bonding to passivate undercoordinated Pb2+, fill halide vacancies, and suppress phase segregation. Its preferential enrichment at the buried interface targets the defect‐rich region, enabling simultaneous wide‐bandgap ...

Managing Crystallization in Tin‐Lead Perovskite Solar Cells via Differential Chelating Coordination

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A chelation‐mediated crystallization strategy is developed for Sn–Pb perovskites using 1,10‐phenanthroline. Stronger coordination with Sn than Pb helps reconcile their mismatched crystallization behavior, leading to improved crystalline quality, fewer defects, and reduced oxidation.
