In article number 2007177, Feng Liu and co‐workers report the fabrication of ternary organic solar cells, achieving a significant J SC boost, by virtue of their optimized crystalline feature, with the formation of eutectic crystalline fibrils. The optimal morphology suppresses energetic disorder and nongeminate recombination, and increases charge transfer and transport, yielding a high efficiency of 17.84% with significant current amplification.
