Stable P‐Type PbS Quantum Dot Ink for all‐Blade‐Coated Short‐Wavelength Infrared Photodiodes

open access: yesAdvanced Materials, EarlyView.
Stabilization of p‐type PbS quantum dot ink is achieved through hydrogen bonding between fluorinated alcohols solvent and the MP ligand, allowing a six‐day shelf‐life. The solvent does not compromise pre‐deposited layers, enabling fully blade‐coated photodiodes in both n–p and p–n architectures, with enhanced detectivity and bandwidth compared to layer‐

Integrated Lead/Iodine Management for Sustainable Perovskite Solar Modules

open access: yesAdvanced Materials, EarlyView.
Perovskite solar modules face environmental risks from lead and iodine leakage. A dual‐function adsorbent—porphyrin‐modified whitlockite nanocomposites—effectively captures iodine and Pb2+, even under severe damage. Combined with a semi‐closed recycling process, it recovers 96.9% high‐purity PbI2 and reduces residual Pb2+ to <10 ppb, offering an ...

Surface chemical polishing and passivation minimize non-radiative recombination for all-perovskite tandem solar cells

open access: yesNature Communications
All-perovskite tandem solar cells have shown great promise in breaking the Shockley–Queisser limit of single-junction solar cells. However, the efficiency improvement of all-perovskite tandem solar cells is largely hindered by the surface defects induced

Exploring wide bandgap metal oxides for perovskite solar cells

open access: yesAPL Materials, 2019
The heterojunction formed when wide bandgap oxides come into contact with perovskite solar cells is essential for high efficiency as it minimizes charge leakage along with charge separation and charge transfer.

Facet‐Selective Electrostatic Assembling of 2D Mxene onto Anisotropic Single‐Crystal Metal Oxides for Enhanced Photocatalysis

open access: yesAdvanced Materials, EarlyView.
Overcoming random aggregation, Facet‐Selective Electrostatic Assembly (FSEA) achieves site‐specific integration of 2D MXenes onto 3D TiO2 supports. This electrostatic assembling creates optimized interface energy junctions that facilitate spatial charge transfer.

Aggregation‐Induced Emission Molecular Design for Mitigating Non‐Radiative Energy Loss in Organic Solar Cells

open access: yesAdvanced Materials, EarlyView.
Aggregation‐induced emission strategy is first used to overcome aggregation‐caused quenching in Y‐series acceptors. By integrating tetraphenylethylene, the dTPE exhibits three‐fold PLQY enhancement and significantly suppressed non‐radiative energy loss. An ultra‐low Eloss of 0.130 eV and a record VOC of 0.93 V are achieved, resulting in a PCE over 20.5%

Polarize the Solvent to Regulate the Intermediate Phase and Dynamic Crystallization of Perovskite Films

open access: yesAdvanced Materials, EarlyView.
A solvent engineering strategy using polar polymers is introduced to regulate perovskite crystallization dynamics in solar cells. Strongly polarized fluorinated groups stabilize the intermediate phase and control solvent exfoliation, leading to high‐quality films with suppressed defects.
