Reducing Interface Energy Loss of Perovskite Solar Cells by Molecular Engineering of Hole‐Transporting Materials

Angewandte Chemie, EarlyView.
This study reports a new hole‐transporting material (WD03) designed via molecular engineering to regulate defect passivation and energy‐level alignment in perovskite solar cells (PSCs). The propeller‐shaped structure ensures balanced charge transport and film quality. Consequently, WD03‐based devices deliver a high open‐circuit voltage of 1.194 V under

Predictive, Data‐Driven Design of Red‐Light Photoredox Catalysts for C─Heteroatom Bond Formation

Angewandte Chemie, EarlyView.
From redox numbers to red light: Donor oxidation and core reduction potentials predict E0‐0 in cyanoarene dyes, guiding selection of an efficient red‐light catalyst, 4MeODPATPN (PC13). Under 620 nm light, PC13 facilitates Ni‐catalyzed C─heteroatom cross‐couplings (C─N, C─O, C─S) with high functional‐group tolerance and reduced hydrodehalogenation ...
