Temperature‐Driven Weak Gel Aggregation of Conjugated Polymers Enables Double‐Fibril Networks for High‐Performance Organic Solar Cells

The solution‐state aggregation of conjugated polymers critically determines the morphology and performance of organic solar cells (OSCs), yet processing optimization remains largely empirical. Here, we establish the sol–gel transition temperature (Tsol–gel), determined by rheology, as a transferable descriptor linking...
