Solid Additive Delicately Controls Morphology Formation and Enables High‐Performance in Organic Solar Cells

Advanced Functional Materials (2023)

Zhong Lian Zhe Sun Seunglok Lee Seonghun Jeong Sungwoo Jung

Abstract Volatile solid additives are an effective strategy for optimizing morphology and improving the power conversion efficiencies (PCEs) of organic solar cells (OSCs). Much research has been conducted to understand the role of solid additives in active layer morphology. However, it is crucial to delve deeper and understand how solid additives affect the entire morphology evolution process, from the solution state to the film state and the thermal annealing stage, which remains unclear. Herein, the use of a highly crystalline solid additive, phenoxathiin (Ph), in D18‐Cl:N3‐based OSCs and study its impact on morphology formation and photovoltaic performance is presented. Owing to its good miscibility with the acceptor N3, Ph additive can not only extend the time for the active layer to form from the solution state to the film state, but also provide sufficient time for acceptor aggregation. After thermal annealing, Ph solid additive volatilizes better aligned the N3 molecules and formed a favorable hybrid morphology. Consequently, the D18‐Cl:N3–based OSC exhibited an outstanding PCE of 18.47%, with an enhanced short‐circuit current of 27.50 mA cm −2 and a fill factor of 77.82%. This research is spurring the development of high‐performance OSCs using solid additives that allow fine control during morphology development.

Catalytic AgF-Initiated Intramolecular 1,3-Sulfonyl Migration of gem-Difluorovinyl Sulfonates to α,α-Difluoro-β-ketosulfones

Organic Letters (2020)

Baojian Xiong Lei Chen Jie Xu Haotian Sun Xiong Li

A 1,3-sulfonyl migration of difluorovinyl sulfonates initiated by a catalytic amount of silver fluoride is presented. α,α-Difluoro-β-ketosulfones were successfully prepared in excellent yields. This method features high chemoselectivity, good functional group tolerance, high atom economy, and mild, environmentally benign reaction conditions. Furthermore, mechanistic experiments indicate that this migration proceeds in an intermolecular pathway and the corresponding sulfinates are possible intermediates.

Stereoselective gem-Difluorovinylation of gem-Difluorinated Cyclopropanes Enabled by Ni/Pd Cooperative Catalysis

ACS Catalysis (2021)

Baojian Xiong Xuemeng Chen Jiangjun Liu Xuemei Zhang Ying Xia

A cross-electrophile coupling between gem-difluorinated cyclopropanes and 2,2-difluorovinyl tosylate via dual Ni/Pd cooperative catalysis under mild reaction conditions is presented. Various structurally unique organofluorine compounds bearing both monofluoroalkene and gem-difluoroalkene moieties can be effectively afforded in good yields with a high (Z)-selectivity. The synthetic utility of this protocol has been successfully demonstrated by the late-stage modification of a series of complex bioactive molecules.

Single-Junction Organic Solar Cell Containing a Fluorinated Heptacyclic Carbazole-Based Ladder-Type Acceptor Affords over 13% Efficiency with Solution-Processed Cross-Linkable Fullerene as an Interfacial Layer

ACS Applied Materials & Interfaces (2019)

Tsung-Wei Chen Chia‐Chih Chang Yu-Tang Hsiao ChoonKee Chan Ling Hong

In this article, a fluorinated heptacyclic dithienocyclopentacarbazole (DTC)-based non-fullerene acceptor (NFA), DTC(4Ph)-4FIC, is synthesized and blended with J71, PBDB-T, and PBDB-TF, featuring complementary absorption and well-matched energy levels. The DTC(4Ph)-4FIC neat film exhibits face-on preference, whereas the nonfluorinated counterpart, DTC(4Ph)-IC, exhibits edge-on preference; this unique feature owing to fluorination in DTC-based NFAs is observed for the first time. More importantly, DTC(4Ph)-4FIC exhibits improved power conversion efficiencies (PCEs) of 10.92 and 10.41% in J71- and PBDB-T-containing devices, while the devices that employed DTC(4Ph)-IC afford PCEs of 7.76 and 9.48%, respectively. Because PBDB-TF is known to exhibit lower energy levels than J71 and PBDB-T, the corresponding device affords a VOC of 0.95 V, a JSC of 18.29 mA cm–2, a FF of 75.70%, and a PCE of 13.15%, which is 20 and 26% higher than J71- and PBDB-T-containing devices. Furthermore, the inverted device containing the PBDB-TF:DTC(4Ph)-4FIC blend is fabricated using cross-linkable fullerene (C-PCBSD) as the cathode interlayer, affording a decent PCE of 13.36%, with a VOC of 0.94 V, a JSC of 20.20 mA cm–2, and a FF of 70.42%.
