Integrated Lead/Iodine Management for Sustainable Perovskite Solar Modules

Advanced 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 ...

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

Advanced 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

Advanced 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%
