摘要：

Achieving high-performance organic photovoltaics (OPVs) hinges on optimizing the phase separation and interfaces within the active layer, which is crucial for efficient charge generation and transport. While a fibril-like phase-separated network has been widely recognized as the desirable morphology across various blend systems, robust methods to consistently achieve this structure remain elusive, limiting further efficiency gains. Here, we introduce a morphological control strategy using an imide-functionalized benzotriazole polymer, PTzBI-dF, within a D18:L8-BO blend to enhance fibrillar mor...
