Abstract Efficient cathode interfacial materials (CIMs) are essential components for effectively enhancing the performance of organic solar cells (OSCs). Although high‐performance CIMs desired to meet requirements various OSCs, potential candidates scarce. Herein, an amino‐functionalized graphdiyne derivative (GDY‐N) is developed, which represents first example GDY that exhibits favorable solubility in alcohol. Utilizing GDY‐N as CIM, outstanding champion PCE 19.30% devices based on...

Morphology control is crucial in achieving high-performance organic solar cells (OSCs) and remains a major challenge the field of OSC. Solid additive an effective strategy to fine-tune morphology, however, mechanism underlying isomeric solid additives on blend morphology OSC performance still vague urgently requires further investigation. Herein, two based pyridazine or pyrimidine as core units, M1 M2, are designed synthesized explore working OSCs. The smaller steric hindrance larger dipole...

Abstract Side‐chain symmetry‐breaking strategy plays an important role in developing photovoltaic materials for high‐efficiency all‐small‐molecule organic solar cells (ASM OSCs). However, the power conversion efficiencies (PCEs) of ASM OSCs still lag behind their polymer‐based counterparts, which can be attributed to difficulties achieving favorable morphology. Herein, two asymmetric porphyrin‐based donors named DAPor‐DPP and DDPor‐DPP were synthesized, presenting stronger intermolecular...

Abstract Double‐reaction‐centers (DRCs) Fenton‐like chemistry with low or zero oxidant addition has garnered increasing attentions due to their alignment the principles of green and sustainable development. However, regulation such processes remains a significant challenge, primarily deficiencies in microscopic interpretation electron migration mechanisms operating addition. In this work, iron single‐atom DRCs catalyst (Fe/N‐SAC) was prepared for internal‐driven system (zero addition)...
