Through the application of GISAXS and GIWAXS techniques, the phase transition and structural ordering processes within the active layer are examined in detail. The research aims to elucidate the interplay between morphology modulation and device performance, ultimately clarifying the structure–property relationships that govern the efficiency of additive-processed OSCs fabricated via ultrasonic spray deposition.
