      abstract     = {Controlling activelayer morphology during drying is pivotal
                      for the simultaneous realization of high efficiency and
                      durability in Yseries organic solar cells (OSCs). Here, we
                      uncover how the physical state of in situ removable (ISR)
                      isomeric additives, oDF (liquid), mDF (quasisolid), and pDF
                      (solid), governs film formation, molecular ordering, and
                      device stability in binary OSCs. Among them, quasisolid mDF
                      functions as a coldsublimating transient structuring agent:
                      it widens earlystage solvent removal window yet accelerates
                      intermediate crystallization, tightens π–π stacking,
                      enlarges coherence length, and programs a favorable vertical
                      phase separation, as resolved by in situ UV–vis, GIWAXS,
                      and depthprofiled spectroscopy. mDF interacts most strongly
                      with L8-BO while fully evaporating from the film, minimizing
                      nonradiative losses and avoiding the adverse impact of
                      residual additives on device stability. Consequently,
                      PM6:L8BO devices reach $19.28\%$ PCE with improved carrier
                      mobility and suppressed trapassisted recombination; applying
                      mDF to D18:L8BO yields $20.08\%.$ Under 1sun illumination at
                      70 °C, mDF extends operational stability to T80 = 477 h,
                      outperforming oDF (58 h), pDF (279 h), and additivefree
                      control (103 h). These results establish
                      physicalstateprogrammed ISR additives as a general route to
                      cooptimize efficiency and stability in OSCs and provide
                      mechanistic guidance for scalable, residuefree morphology
                      control.},
