Abstract Ternary organic solar cells (T‐OSCs) have attracted significant attention as high‐performance devices. In recent years, T‐OSCs achieved remarkable progress with power conversion efficiency (PCE) exceeding 19%. However, the introduction of third component complicates intermolecular interaction compared to binary blend, resulting in poor controllability active layer and limiting performance improvement. To address these issues, dual‐functional components been developed that not only broaden spectral range but also optimize morphology. this review, effect on expanding absorption is first discussed.

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.
