Volatilizable Solid Additive‐Assisted Treatment Enables Organic Solar Cells with Efficiency over 18.8% and Fill Factor Exceeding 80%

by Sunan Bao, Hang Yang, Hongyu Fan, Jianqi Zhang, Zhixiang Wei, Chaohua Cui, Yongfang Li

A new morphology control approach is developed to fabricate high-performance organic solar cells by utilizing the synergistic effect of 1-chloronaphthalene (CN) and dithieno[3,2-b:2′,3′-d]thiophene (DTT) additives. This approach exhibits general application in various active layer systems to achieve well-developed morphology, enabling outstanding power-conversion efficiency over 18.8% and fill factor exceeding 80% for the device based on PTQ10:m-BTP-PhC6:PC₇₁BM.

Abstract

Controlling the self-assembling of organic semiconductors to form well-developed nanoscale phase separation in the bulk-heterojunction active layer is critical yet challenging for building high-performance organic solar cells (OSCs). Particularly, the similar anisotropic conjugated structures between nonfullerene acceptors and p-type organic semiconductor donors raise more complexity on manipulating their aggregation toward appropriate phase separation. Herein, a new approach to tune the morphology of photoactive layer is developed by utilizing the synergistic effect of dithieno[3,2-b:2′,3′-d]thiophene (DTT) and 1-chloronaphthalene (CN). The volatilizable solid additive DTT with high crystallinity can restrict the over self-assembling of nonfullerene acceptors during the film casting process, and then allowing the refining of phase separation and molecular packing with the simultaneous volatilization of DTT under thermal annealing. Consequently, the PTQ10:m-BTP-PhC6:PC₇₁BM-based ternary OSCs processed by the dual additives of CN and DTT record a notable power-conversion efficiency of 18.89%, with a remarkable FF of 80.6%.

Research Progress of Intramolecular π‐Stacked Small Molecules for Device Applications

by Sheng‐Yi Yang, Yang‐Kun Qu, Liang‐Sheng Liao, Zuo‐Quan Jiang, Shuit‐Tong Lee

Unlike traditional covalent bond-connected conjugated molecules, π-stacked small molecules have special advantages in organic semiconductors. This review mainly focuses on the research development of π-stacked molecular systems and introduces the new characteristics brought by the special molecular configuration and its application in organic semiconductors.

Abstract

Organic semiconductors can be designed and constructed in π-stacked structures instead of the conventional π-conjugated structures. Through-space interaction (TSI) occurs in π-stacked optoelectronic materials. Thus, unlike electronic coupling along the conjugated chain, the functional groups can stack closely to facilitate spatial electron communication. Using π-stacked motifs, chemists and materials scientists can find new ways for constructing materials with aggregation-induced emission (AIE), thermally activated delayed fluorescence (TADF), circularly polarized luminescence (CPL), and room-temperature phosphorescence (RTP), as well as enhanced molecular conductance. Organic optoelectronic devices based on π-stacked molecules have exhibited very promising performance, with some of them exceeding π-conjugated analogues. Recently, reports on various organic π-stacked structures have grown rapidly, prompting this review. Representative molecular scaffolds and newly developed π-stacked systems could stimulate more attention on through-space charge transfer the well-known through-bond charge transfer. Finally, the opportunities and challenges for utilizing and improving particular materials are discussed. The previous achievements and upcoming prospects may provide new insights into the theory, materials, and devices in the field of organic semiconductors.

The key challenges and perspectives of TTA upconversion systems for further improvement for optoelectronic devices and other related research directions are provided. This review hopes to provide valuable guidelines for future advancement in organic optoelectronics.

Abstract

Organic semiconductor materials have been widely used in various optoelectronic devices due to their rich optical and/or electrical properties, which are highly related to their excited states. Therefore, how to manage and utilize the excited states in organic semiconductors is essential for the realization of high-performance optoelectronic devices. Triplet–triplet annihilation (TTA) upconversion is a unique process of converting two non-emissive triplet excitons to one singlet exciton with higher energy. Efficient optical-to-electrical devices can be realized by harvesting sub-bandgap photons through TTA-based upconversion. In electrical-to-optical devices, triplets generated after the combination of electrons and holes also can be efficiently utilized via TTA, which resulted in a high internal conversion efficiency of 62.5%. Currently, many interesting explorations and significant advances have been demonstrated in these fields. In this review, a comprehensive summary of these intriguing advances on developing efficient TTA upconversion materials and their application in optoelectronic devices is systematically given along with some discussions. Finally, the key challenges and perspectives of TTA upconversion systems for further improvement for optoelectronic devices and other related research directions are provided. This review hopes to provide valuable guidelines for future related research and advancement in organic optoelectronics.

Organic Electrochemical Transistors for In Vivo Bioelectronics

by Ali Nawaz, Qian Liu, Wei Lin Leong, Kathryn E. Fairfull‐Smith, Prashant Sonar

The role of organic electrochemical transistors in different in vivo bioelectronic applications, ranging from human electrophysiology to plant interfacing, is discussed. Particular emphasis is given on analyzing the key materials design and device design aspects that make these devices ideal for addressing future in vivo biological systems. Finally, some challenges, limitations, and future applications are critically assessed.

Abstract

Organic electrochemical transistors (OECTs) are presently a focus of intense research and hold great potential in expanding the horizons of the bioelectronics industry. The notable characteristics of OECTs, including their electrolyte-gating, which offers intimate interfacing with biological environments, and aqueous stability, make them particularly suitable to be operated within a living organism (in vivo). Unlike the existing in vivo bioelectronic devices, mostly based on rigid metal electrodes, OECTs form a soft mechanical contact with the biological milieu and ensure a high signal-to-noise ratio because of their powerful amplification capability. Such features make OECTs particularly desirable for a wide range of in vivo applications, including electrophysiological recordings, neuron stimulation, and neurotransmitter detection, and regulation of plant processes in vivo. In this review, a systematic compilation of the in vivo applications is presented that are addressed by the OECT technology. First, the operating mechanisms, and the device design and materials design principles of OECTs are examined, and then multiple examples are provided from the literature while identifying the unique device properties that enable the application progress. Finally, one critically looks at the future of the OECT technology for in vivo bioelectronic applications.

Emissive Charge‐Transfer States at Hybrid Inorganic/Organic Heterojunctions Enable Low Non‐Radiative Recombination and High‐Performance Photodetectors

by Flurin Eisner, Georgie Foot, Jun Yan, Mohammed Azzouzi, Dimitra G. Georgiadou, Wai Yu Sit, Yuliar Firdaus, Guichuan Zhang, Yen‐Hung Lin, Hin‐Lap Yip, Thomas D. Anthopoulos, Jenny Nelson

Efficient charge generation mediated by an emissive charge-transfer state is observed in hybrid heterojunctions comprising the inorganic semiconductor copper thiocyanate and common organic semiconductors. This enables the fabrication of solar cells with very low voltage losses and highly sensitive photodetectors that can detect sub-picowatt near-infrared light.

Abstract

Hybrid devices based on a heterojunction between inorganic and organic semiconductors have offered a means to combine the advantages of both classes of materials in optoelectronic devices, but, in practice, the performance of such devices has often been disappointing. Here, it is demonstrated that charge generation in hybrid inorganic–organic heterojunctions consisting of copper thiocyanate (CuSCN) and a variety of molecular acceptors (ITIC, IT-4F, Y6, PC₇₀BM, C₇₀, C₆₀) proceeds via emissive charge-transfer (CT) states analogous to those found at all-organic heterojunctions. Importantly, contrary to what has been observed at previous organic–inorganic heterojunctions, the dissociation of the CT-exciton and subsequent charge separation is efficient, allowing the fabrication of planar photovoltaic devices with very low non-radiative voltage losses (0.21 ± 0.02 V). It is shown that such low non-radiative recombination enables the fabrication of simple and cost-effective near-IR (NIR) detectors with extremely low dark current (4 pA cm⁻²) and noise spectral density (3 fA Hz^−1/2) at no external bias, leading to specific detectivities at NIR wavelengths of just under 10¹³ Jones, close to the performance of commercial silicon photodetectors. It is believed that this work demonstrates the possibility for hybrid heterojunctions to exploit the unique properties of both inorganic and organic semiconductors for high-performance opto-electronic devices.

Organic Single Crystals with High Photoluminescence Quantum Yields Close to 100% and High Mobility for Optoelectronic Devices

by Jingwei Tao, Dan Liu, Jiangbo Jing, Huanli Dong, Leijing Liu, Bin Xu, Wenjing Tian

Organic single crystals based on 9,10-bis([N,N-diphenyl]-4′-phenylethynyl)anthracene (TPA-An) and 9,10-bis([1′,3′-diphenyl]-5′-phenylethynyl)anthracene (TBA-An) exhibit high photoluminescence quantum yields close to 100% and ultrahigh hole mobilities of 0.45 and 0.15 cm² V⁻¹ s⁻¹ in single-crystal organic field-effect transistors. Simultaneously, the TPA-An-based and TBA-An-based single-crystal phototransistors have ultrahigh sensitivity to 370 nm UV light.

Abstract

Organic single crystals with excellent optical and electrical properties are critical for the development of organic optoelectronics. Herein, two compounds 9,10-bis([N,N-diphenyl]-4′-phenylethynyl)anthracene (TPA-An) and 9,10-bis([1′,3′-diphenyl]-5′-phenylethynyl)anthracene (TBA-An) are synthesized by introducing two different luminescent groups, triphenylamine and 1,3-diphenylbenzene, at the 9,10 positions of anthracene via triple bond connection. Single crystals based on TPA-An and TBA-An with a ribbon morphology obtained through the slow solvent-evaporation method exhibit high photoluminescence quantum yields (PLQYs) of 98% and 99% at room temperature, and remarkable hole mobilities of 0.45 and 0.15 cm² V⁻¹ s⁻¹ in single-crystal organic field-effect transistors (SC-OFETs). Furthermore, UV phototransistors based on the two single crystals obtain photosensitivities of 1.03 × 10³ and 3.45 × 10⁴, ultrahigh photoresponsivities of 7.19 × 10⁵ and 1.50 × 10⁵ A W⁻¹, and the detectivities exceeding 1.40 × 10¹⁶ and 1.60 × 10¹⁷ Jones.

Slip‐Stacked J‐Aggregate Materials for Organic Solar Cells and Photodetectors

by Jin Hong Kim, Tim Schembri, David Bialas, Matthias Stolte, Frank Würthner

J- and H-aggregates constitute archetype functional materials due to unique properties originating from exciton coupling. Here, a broader perspective on the origin of red-shifted absorption bands including intermolecular charge transfer-mediated J-coupling is provided. Further, important classes of dye aggregates with regard to the prevailing intermolecular couplings and their relevance for organic solar cells and photodetectors are analyzed.

Abstract

Dye–dye interactions affect the optical and electronic properties in organic semiconductor films of light harvesting and detecting optoelectronic applications. This review elaborates how to tailor these properties of organic semiconductors for organic solar cells (OSCs) and organic photodiodes (OPDs). While these devices rely on similar materials, the demands for their optical properties are rather different, the former requiring a broad absorption spectrum spanning from the UV over visible up to the near-infrared region and the latter an ultra-narrow absorption spectrum at a specific, targeted wavelength. In order to design organic semiconductors satisfying these demands, fundamental insights on the relationship of optical properties are provided depending on molecular packing arrangement and the resultant electronic coupling thereof. Based on recent advancements in the theoretical understanding of intermolecular interactions between slip-stacked dyes, distinguishing classical J-aggregates with predominant long-range Coulomb coupling from charge transfer (CT)-mediated or -coupled J-aggregates, whose red-shifts are primarily governed by short-range orbital interactions, is suggested. Within this framework, the relationship between aggregate structure and functional properties of representative classes of dye aggregates is analyzed for the most advanced OSCs and wavelength-selective OPDs, providing important insights into the rational design of thin-film optoelectronic materials.

Construction of Carbon Dots with Color‐Tunable Aggregation‐Induced Emission by Nitrogen‐Induced Intramolecular Charge Transfer

by Xiaokai Xu, Luoqi Mo, Yadong Li, Xiaoqin Pan, Guangqi Hu, Bingfu Lei, Xuejie Zhang, Mingtao Zheng, Jianle Zhuang, Yingliang Liu, Chaofan Hu

Carbon dots (CDs) with multicolor aggregation-induced emission exhibit dual fluorescence emission at 480 and 580 nm, which is related to the SS bonds of DTSA and the conjugated structure attached to CO/CN bonds, respectively. With the increase of CN content from 35.6% to 58.4%, the intramolecular charge transfer efficiency increases from 8.71% to 45.94%, changing the fluorescence of the CDs from green to red.

Abstract

As one of the most promising fluorescent nanomaterials, the fluorescence of carbon dots (CDs) in solution is extensively studied. Nevertheless, the synthesis of multicolor solid-state fluorescence (SSF) CDs is rarely reported. Herein, CDs with multicolor aggregation-induced emission are prepared using amine molecules, all of them exhibiting dual fluorescence emission at 480 nm (Em-1) and 580–620 nm (Em-2), which is related to the SS bonds of dithiosalicylic acid and the conjugated structure attached to CO/CN bonds, respectively. As a strong electron-withdrawing group, the increase of CN content makes dual-fluorescent groups on the surface of CDs produce push and pull electrons, which determines intramolecular charge transfer (ICT) between the double emission. With the increase in CN content from 35.6% to 58.4%, the ICT efficiency increases from 8.71% to 45.94%, changing the fluorescence of CDs from green to red. The increase of ICT efficiency causes fluorescence quantum yield enhancement by nearly five times and redshift of the fluorescence peak. Finally, based on the multicolor luminescence properties induced by the aggregation of CDs, pattern encryption and white-LED devices are realized. Based on the fat solubility and strong ultraviolet absorption characteristics of CDs, fingerprint detection and leaf anti-UV hazards are applied.
