All‐polymer solar cells (all‐PSCs) possess excellent operation stability and mechanical robustness than other types of organic solar cells, thereby attracting considerable attention for wearable flexible electron devices. However, the power conversion efficiencies (PCEs) of all‐PSCs are still lagging behind those of small‐molecule‐acceptor‐based systems owing to the limitation of photoactive materials and unsatisfactory blend morphology. Herein, a novel terpolymer denoted as PBDB‐TFCl (poly4,8‐bis(5‐(2‐ethylhexyl)‐4‐fluorothiophen‐2‐yl)benzo[1,2‐b:4,5‐b″]dithiophene‐1,3‐bis(2‐ethylhexyl)‐5,7‐di(thiophen‐2‐yl)‐4H,8H‐benzo[1,2‐c:4,5‐c″]dithiophene‐4,8‐dione‐4,8‐bis(4‐chloro‐5‐(2‐ethylhexyl)thiophen‐2‐yl)benzo[1,2‐b:4,5‐b']dithiophene) was used as an electron donor coupled with a ternary strategy to optimize the performance of all‐PSCs. The addition of PBDB‐TCl unit deepened the highest occupied molecular orbital energy level, reducing voltage losses. Moreover, the introduction of the guest donor (D18‐Cl) effectively regulated the phase transition kinetics of PBDB‐TFCl:D18‐Cl:PY‐IT during the film formation, leading to ideal size of aggregations and enhanced crystallinity. PBDB‐TFCl:D18‐Cl:PY‐IT devices exhibited a PCE of 18.6% (certified as 18.3%), judged as the highest value so far obtained with all‐PSCs. Besides, based on the ternary activelayer, the manufactured 36 cm2 flexible modules exhibited a PCE of 15.1%. Meanwhile, the ternary PSCs exhibited superior photostability and mechanical stability. In sum, the proposed strategy based on molecular design and ternary strategy allowed optimizing all‐polymer blend morphology and improving the photovoltaic performance for stable large‐scale flexible PSCs.This article is protected by copyright.

“…In recent years, several alcoholprocessed PEDOT:PSS derivatives are developed, exhibiting low acidity and improved wettability on hydrophobic surface. [54][55][56] However, the alcohol-processed PEDOT:PSS derivatives usually show inferior hole collection ability, leading to unsatisfied OSC performances. Therefore, the processability and wettability of PE-DOT:PSS need to be further improved.…”

Solution‐processed hole transporting layers (HTLs) not only play a crucial role in realizing high performance of organic solar cells (OSCs), but also possess excellent compatibility with low‐cost and large‐area processing methods of industrialized productions. However, the number and species of HTL materials are obviously fewer than that of electron‐transporting materials, which limits the development and application of OSCs. In particular, the large energy level difference between anode and organic active layer leads to the serious energy barrier for hole collection, bringing much difficulty in developing efficient HTL materials. In this review, it is focused on the recent advances in solution‐processed HTLs in OSCs. Initially, the working mechanism, property requirement, and existing issues of solution‐processed HTLs are systematically analyzed. Afterward, the main classes of solution‐processed HTL materials are discussed, including PEDOT:PSS, conjugated polyelectrolytes (CPEs), TMOs, and others. The structure‐property relationships of solution‐processed HTL materials are analyzed, and some important design rules for such materials toward efficient and stable OSCs are presented. Finally, a brief summary is presented along with some perspectives to help researchers understanding the challenges and opportunities in this field.

[16][17][18][19][20][21][22] The PEDOT:PSS CP is typically synthesized through the oxidative polymerization of 3,4-ethylenedioxythiophene (EDOT) in an aqueous solution containing PSS polyanions. Over the past decades, significant efforts have been dedicated to the development of novel polyanions as substitutes for PSS in order to fabricate high-performance PEDOT CPs.…”
