  1. Tailoring Pore Size of Nitrogen-Doped Hollow Carbon Nanospheres for Confining Sulfur in Lithium–Sulfur Batteries

    Weidong Zhou, Chongmin Wang, Qinglin Zhang, Héctor D. Abruña, Yang He, Jiangwei Wang, Scott X. Mao and Xingcheng Xiao

    Article first published online: 29 JAN 2015 | DOI: 10.1002/aenm.201401752

    Three types of nitrogen-doped hollow carbon spheres with different pore sized porous shells are prepared to investigate the performance of sulfur confinement. The reason that why no sulfur is observed in previous research is determined and it is successfully demonstrated that the sulfur/polysulfide will overflow the porous carbon during the lithiation process.

  2. Identifying the Optimum Morphology in High-Performance Perovskite Solar Cells

    Guijun Li, Kwong Lung Ching, Jacob Y. L. Ho, Man Wong and Hoi-Sing Kwok

    Article first published online: 29 JAN 2015 | DOI: 10.1002/aenm.201401775

    The study of the perovskite solar cells provides insight into the optimum morphology. A bilayer structure is required for efficient solar cells, and one with a high efficiencies of up to 15.2% and an open-circuit voltage (Voc) up to 1110 mV is demonstrated. Furthermore, the 80% high yield also paves the way for the possibility of mass production in the future.

  3. Interplay Between Side Chain Pattern, Polymer Aggregation, and Charge Carrier Dynamics in PBDTTPD:PCBM Bulk-Heterojunction Solar Cells

    Clare Dyer-Smith, Ian A. Howard, Clément Cabanetos, Abdulrahman El Labban, Pierre M. Beaujuge and Frédéric Laquai

    Article first published online: 29 JAN 2015 | DOI: 10.1002/aenm.201401778

    The polymer side chain pattern determines the efficiency of PBDTTPD:phenyl-C61/71-butyric acid methyl ester solar cells because it changes the yield of free charges and the nongeminate recombination dynamics, as demonstrated by broadband transient pump–probe spectroscopy. Tuning of the side chains leads to a doubling of the power conversion efficiency from 4% up to 8%.

  4. Quantitative and Qualitative Determination of Polysulfide Species in the Electrolyte of a Lithium–Sulfur Battery using HPLC ESI/MS with One-Step Derivatization

    Dong Zheng, Deyu Qu, Xiao-Qing Yang, Xiqian Yu, Hung-Sui Lee and Deyang Qu

    Article first published online: 29 JAN 2015 | DOI: 10.1002/aenm.201401888

    The polysulfide species dissolved in aprotic solutions can be separated and analyzed by reverse phase (RP) high performance liquid chromatography (HPLC) in tandem with electrospray-mass spectroscopy. The relative distribution of polysulfide species in the electrolyte recovered from Li–S batteries is quantitatively and reliably determined for the first time.

    Quantum Dots: Enhanced Photovoltaic Performance of Inverted Polymer Solar Cells Utilizing Multifunctional Quantum-Dot Monolayers (Adv. Energy Mater. 2/2015)

    Byung Joon Moon, Sungjae Cho, Kyu Seung Lee, Sukang Bae, Sanghyun Lee, Jun Yeon Hwang, Basavaraj Angadi, Yeonjin Yi, Min Park and Dong Ick Son

    Article first published online: 21 JAN 2015 | DOI: 10.1002/aenm.201570011

    In article number 1401130, Dong Ick Son and co-workers demonstrate inverted polymer solar cells (iPSCs) containing a quantum dot (QD) monolayer that bonds with the low-work function (WF) organic material polyethylenimine ethoxylated (PEIE) by electrostatic interaction. The PEIE/monolayered QD heterostructures serve as the electron transport layer, absorption layer, and surface plasmon resonance (SPR) trigger for improving photovoltaic performance. The iPSCs enhance the power conversion efficiency (PCE) more than 20%, with an 8.1% maximum PCE.
