Simply planarizing nonfused perylene diimide based acceptors toward promising non-fullerene solar cells

Bian, Gao-Feng; Zhao, Feng; Lau, Tsz-Ki; Sheng, Chun-Qi; Lu, Xinhui; Du, Hui; Zhang, Cheng; Qu, Zhi-Rong; Chen, Hongzheng; Wan, Jun-Hua

This work focuses on developing high-efficiency perylene diimide (PDI)-based small molecular nonfullerene acceptors with a simple synthetic strategy. We reported a new electron acceptor, Py-e-PDI, obtained via cross-coupling four PDI units with a planar pyrene core through ethynyl groups. Although the ring-fusion synthetic procedure was omitted, the large planar core…

High-performance polyurethane nanocomposites based on UPy-modified cellulose nanocrystals

Tian, Donglin; Wang, Fenfen; Yang, Zhijun; Niu, Xiling; Wu, Qiang; Sun, Pingchuan

Densely H-bonding assemblies are the key strategy found by nature to enhance the rupture strength of natural polymers without sacrificing their toughness, such as spider silk, while it still remains a great challenge using such intriguing strategy to prepare high-performance synthesized polymer or biopolymer enhanced polymer nanocomposites. To address this…

Single-Junction Organic Solar Cell with over 15% Efficiency Using Fused-Ring Acceptor with Electron-Deficient Core

Yuan, Jun; Zhang, Yunqiang; Zhou, Liuyang; Zhang, Guichuan; Yip, Hin-Lap; Lau, Tsz-Ki; Lu, Xinhui; Zhu, Can; Peng, Hongjian; Johnson, Paul A.; Leclerc, Mario; Cao, Yong; Ulanski, Jacek; Li, Yongfang; Zou, Yingping

Summary Recently, non-fullerene n-type organic semiconductors have attracted significant attention as acceptors in organic photovoltaics (OPVs) due to their great potential to realize high-power conversion efficiencies. The rational design of the central fused ring unit of these acceptor molecules is crucial to maximize device performance. Here, we report a new…

Charge carrier transport and nanomorphology control for efficient non-fullerene organic solar cells

Hu, Hanlin; Deng, Wanyuan; Qin, Minchao; Yin, Hang; Lau, Tsz-Ki; Fong, Patrick W. K.; Ren, Zhiwei; Liang, Qiong; Cui, Li; Wu, Hongbin; Lu, Xinhui; Zhang, Weimin; McCulloch, Iain; Li, Gang

Single junction organic photovoltaic devices (OPVs) have exceeded 15% power conversion efficiency (PCE) with the help of fused ring based low-bandgap non-fullerene acceptors (NFAs). As a major type of NFA, the indacenodithiophene derivative NFA (IDTBR) has been shown to have superior OPV stability with outstanding VOC, but the efficiency is…

Fused thienobenzene-thienothiophene electron acceptors for organic solar cells

Xu, Ye; Jiang, Haotian; Lau, Tsz-Ki; Zhu, Jingshuai; Wang, Jiayu; Lu, Xinhui; Zhan, Xiaowei; Lin, Yuze

Small molecule ladder-type heteroarenes IHBT-2F is designed and synthesized with strong electron-donating and molecular packing properties, where the central unit, fused thienobenzene-thienothiphene (IHBT), is attached with the strong electron-deficient 2-(5,6-difluoro-3-oxo-2,3-dihydro-1H-inden-1-ylidene)malononitrile (2FIC) as the end group. The counterpart IDBT-2F with…

Tailoring vertical phase distribution of quasi-two-dimensional perovskite films via surface modification of hole-transporting layer

Liu, Tiefeng; Jiang, Youyu; Qin, Minchao; Liu, Junxue; Sun, Lulu; Qin, Fei; Hu, Lin; Xiong, Sixing; Jiang, Xueshi; Jiang, Fangyuan; Peng, Ping; Jin, Shengye; Lu, Xinhui; Zhou, Yinhua

Vertical phase distribution plays an important role in the quasi-two-dimensional perovskite solar cells. So far, the driving force and how to tailor the vertical distribution of layer numbers have been not discussed. In this work, we report that the vertical distribution of layer numbers in the quasi-two-dimensional perovskite films deposited…

Two-dimensional inverted planar perovskite solar cells with efficiency over 15% via solvent and interface engineering

Lian, Xiaomei; Chen, Jiehuan; Zhang, Yingzhu; Tian, Shuoxun; Qin, Minchao; Li, Jun; Andersen, Thomas Rieks; Wu, Gang; Lu, Xinhui; Chen, Hongzheng

High short-circuit current (Jsc) and open-circuit voltage (Voc) are both required for two-dimensional (2D) perovskite solar cells (PVSCs) with high power conversion efficiency (PCE). In this work, solvent engineering is combined with interface engineering to fabricate 2D PVSCs with enhanced Jsc and Voc. Mixing formamide with N,N-dimethylformamide (DMF) was found…

The structure of spray-dried detergent powders

Farshchi, Amin; Hassanpour, Ali; Bayly, Andrew E.

The complex multiscale structure of spray dried detergent granules has been characterized using a complementary range of techniques including scanning electron microscopy (SEM), image analysis, wide angle and small angle X-ray scattering (WAXS, SAXS) and X-ray microtomography. A complex composite structure is revealed due to the multiphase nature of the…

Room-Temperature Meniscus Coating of >20% Perovskite Solar Cells: A Film Formation Mechanism Investigation

Hu, Hanlin; Ren, Zhiwei; Fong, Patrick W. K.; Qin, Minchao; Liu, Danjun; Lei, Dangyuan; Lu, Xinhui; Li, Gang

Perovskite solar cells (PSCs) are ideally fabricated entirely via a scalable solution process at low temperatures to realize the promise of simple manufacturing, low-cost processing, compatibility with flexible substrates, and perovskite-based tandem solar cells. However, high-quality photoactive perovskite thin films under those processing conditions is a challenge. Here, a laminar…

PrP (58–93) peptide from unstructured N-terminal domain of human prion protein forms amyloid-like fibrillar structures in the presence of Zn2+ ions

Gielnik, Maciej; Pietralik, Zuzanna; Zhukov, Igor; Szymańska, Aneta; Kwiatek, Wojciech M.; Kozak, Maciej

Many transition metal ions modulate the aggregation of different amyloid peptides. Substoichiometric zinc concentrations can inhibit aggregation, while an excess of zinc can accelerate the formation of cytotoxic fibrils. In this study, we report the fibrillization of the octarepeat domain to amyloid-like structures. Interestingly, this self-assembling process occurred only in…
