Surface modification of ZnO electron transport layers with glycine for efficient inverted non-fullerene polymer solar cells
Zhu, Xiaoqian; Guo, Bing; Fang, Jin; Zhai, Tianshu; Wang, Yanan; Li, Guangwei; Zhang, Jianqi; Wei, Zhixiang; Duhm, Steffen; Guo, Xia; Zhang, Maojie; Li, Yongfang
Interfacial engineering is crucial to improve the photovoltaic performance of polymer solar cells (PSCs). In this study, we demonstrate efficient inverted non-fullerene PSCs with ZnO modified by nontoxic glycine (Gly) as the electron transport layer (ETL). With the modification of Gly, work function of the ETL interlayer was decreased from…

Revisiting the Role of Graphene Quantum Dots in Ternary Organic Solar Cells: Insights into the Nanostructure Reconstruction and Effective Förster Resonance Energy Transfer
Sung, Sae Jin; Kim, Jae Ho; Gihm, Se Hoon; Park, Jisoo; Cho, Young Shik; Yang, Seung Jae; Park, Chong Rae
Recent studies have introduced the graphene quantum dot (GQD) as a third material for the bulk-heterojunction polymer:fullerene solar cell (PSC) to improve light conversion efficiency. Although exciton generation/dissociation and carrier transport in the GQD-incorporated light-absorbing layer are strongly influenced by the ternary component, detailed analysis on the role of GQD…

Cast-and-Use Super Black Coating Based on Polymer-Derived Hierarchical Porous Carbon Spheres
Guo, Jing; Li, Dongdong; Zhao, Han; Zou, Weizhi; Yang, Zhusheng; Qian, Zhenchao; Yang, Shijia; Yang, Meng; Zhao, Ning; Xu, Jian
Super black materials with extremely low reflectance and high absorption of incident light are crucial in various applications with strict optical requirements. However, the existing super black materials suffer from technical complexity in practical use whereas the underlying physics of their ultralow reflectance is still unclear. Herein, hierarchical porous carbon…

Mechanical Properties and Failure Behavior of Physically Assembled Triblock Copolymer Gels with Varying Midblock Length
Mishra, Satish; Prado, Rosa M. Badani; Zhang, Song; Lacy, Thomas E.; Gu, Xiaodan; Kundu, Santanu
Mechanical properties including the failure behavior of physically assembled gels or physical gels are governed by their network structure. To investigate such behavior, we consider a physical gel system consisting of poly(styrene)-poly(isoprene)-poly(styrene) in mineral oil. In these gels, the endblock (PS) molecular weights are not significantly different, whereas, the midblock…

Rheological modifiers based on supramolecular block copolymers: From weak associations to interconnected micelles
Goldansaz, Hadi; Jangizehi, Amir; Nikravan, Goolia; Verkinderen, Olivier; Goderis, Bart; Ghaffarian, Seyed Reza; van Ruymbeke, Evelyne; Ahmadi, Mostafa
The rheological spectra of poly(n-butyl acrylate) in the presence of a series of P(nBA-b-HEMA) rheology modifiers show a two-step relaxation process originating from the PnBA matrix and the self-assemblies. The HEMA segments are further grafted with strong, hydrogen bonding UPy groups, which both magnifies and slows down the relaxation of…

Polymer-Induced Modification of Cellulose Nanocrystal Assemblies in Aqueous Suspensions
Cohen, Neta; Ochbaum, Guy; Levi-Kalisman, Yael; Bitton, Ronit; Yerushalmi-Rozen, Rachel
The effect of adsorbing, nonionic polymers on the phase behavior of cellulose nanocrystals (CNCs) is of interest for design and preparation of functional hybrids. CNC assembly into a chiral nematic phase (N*) was investigated in the presence of highly hydrated poly(vinyl alcohol) (HPVA), low hydrated PVA (LPVA), and poly(vinylpyrrolidone) (PVP).…
