ABSTRACT All‐polymer solar cells (all‐PSCs) are of interest owing to their unique advantages, including remarkably improved device stability and exceptional mechanical stretchability. Over recent years, there has been a notable increase in the power conversion efficiency (PCE) all‐PSCs, largely attributed advancements morphology control active layer. Notably, domain size is paramount importance as it impacts critical factors such exciton dissociation, charge transport, collection. However, low glass transition temperature conjugated polymers, coupled with minimal change mixing entropy, often results an excessive degree phase separation.

Abstract Pseudo‐planar heterojunction (PPHJ) structure using sequential deposition is an effective method for achieving high‐efficiency organic photovoltaics (OPVs). The crystallization and phase separation behavior during film‐forming process intricately related to morphology with PPHJ structure. Despite this, the relationship between these two factors remains ambiguous, thereby impeding further improvements in performance.
