Abstract The hole‐transporting material (HTM), poly (3,4‐ethylene dioxythiophene) poly(styrene sulfonate) (PEDOT : PSS), is the most widely used in realization of high‐efficiency organic solar cells (OSCs). However, stability PEDOT PSS‐based OSCs quite poor, arising from its strong acidity and hygroscopicity. In addition, PSS has an absorption infrared region high highest occupied molecular orbital (HOMO) energy level, thus limiting enhancement short‐circuit current density ( J sc ) open‐circuit voltage V oc ), respectively. Herein, two asymmetric self‐assembled molecules (SAMs), namely BrCz BrBACz, were designed synthesized as HTM binary based on well‐known system PM6 Y6, eC9, L8‐BO, D18 eC9. Compared with BrCz, BrBACz shows larger dipole moment, deeper work function lower surface energy. Moreover, not only enhances photon harvesting active layer, but also minimizes losses well improves interface charge extraction/ transport. Consequently, eC9‐based OSC using exhibits a champion efficiency 19.70 % remarkable 29.20 mA cm −2 0.856 V, which record for so far. unencapsulated device maintains 95.0 original after 1,000 hours storage at air ambient, indicating excellent long‐term stability.

Abstract Organic solar cells (OSCs) have emerged as promising candidates for renewable energy harvesting due to their lightweight, flexible, and low‐cost fabrication potential. The efficiency of OSCs is largely determined by the choice solvents, which significantly affect film morphology active layers, intermixed donor‐acceptor domains, overall device performance. Beginning with an introduction importance solvent selection, screening classification emphasizing characteristics based on sustainability, solubility, other additional considerations are explored. Various non‐halogenated highlighting commonly used aromatic biomass‐derived water/alcohol‐based solvents state‐of‐the‐art donor acceptor materials, focusing efficient materials such PM6 D18, high‐performing Y‐series acceptors also presented. Strategies developing high‐performance processed using examined, including engineering additive additive‐free approaches, ternary strategies, layer‐by‐layer techniques. large‐area devices addressed, blade‐coating, slot‐coating, processing Finally, this review outlines future research directions in OSCs, need continuous innovation overcome existing limitations propel OSC technology toward commercial viability.
