Optimizing Molecular Packing and Film Morphology in Organic Solar Cells via Additive‐Modulated Growth Processes

Advanced Energy Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 30, 2024

Abstract Controlling the packing feature and film morphology of active layers is precondition for achieving highly efficient organic solar cells (OSCs). The growth transition donors acceptors from solution to solid films plays an intrinsic role in shaping these features. In this study, two simple additives, cyanobenzene (CNB) 1,4‐dicyanobenzene (DCNB), are presented modulate process investigate impact behaviors on molecule quality, morphology, device performances. Both additives prolong nucleation period layers, resulting improved molecular domain purity, crystallization. This optimization enhances charge extraction efficiency as well reduces recombination losses. Consequently, devices based D18:BTP‐eC9‐4F processed with obtain a 19.43% power conversion (PCE). Furthermore, PCE 14.35% achieved bladed‐coated modules 5 cm × substrates. These findings underscore importance processes quality illustrate their fundamental relationship, which promises further advancements OSC technology.
