  1. Growth Engineering of CH3NH3PbI3 Structures for High-Efficiency Solar Cells

    M. Ibrahim Dar, Mojtaba Abdi-Jalebi, Neha Arora, Michael Grätzel and Mohammad Khaja Nazeeruddin

    Article first published online: 26 NOV 2015 | DOI: 10.1002/aenm.201501358

    The presence of a small amount of PbCl2 in PbI2 precursor solution not only influences the growth and properties of CH3NH3PbI3 structures, but also leads to the enhancement of power conversion efficiency to >16%.

  2. Co–Ni-Based Nanotubes/Nanosheets as Efficient Water Splitting Electrocatalysts

    Siwen Li, Yongcheng Wang, Sijia Peng, Lijuan Zhang, Abdullah M. Al-Enizi, Hui Zhang, Xuhui Sun and Gengfeng Zheng

    Article first published online: 26 NOV 2015 | DOI: 10.1002/aenm.201501661

    Homologous Co–Ni-based nanotube/nanosheet structures with tunable Co/Ni ratios are grown on conductive substrates with a cation-exchanging method to grow hydroxides as oxygen evolution reaction (OER) catalysts, followed by anion exchanging to obtain corresponding nitrides as hydrogen evolution reaction (HER) catalysts. They exhibit low overpotentials, small Tafel slopes, and ultrahigh current densities, serving as promising, efficient, and stable electrocatalysts for water splitting.

  3. Fill Factor Losses in Cu2ZnSn(SxSe1−x)4 Solar Cells: Insights from Physical and Electrical Characterization of Devices and Exfoliated Films

    Kong Fai Tai, Oki Gunawan, Masaru Kuwahara, Shi Chen, Subodh Gautam Mhaisalkar, Cheng Hon Alfred Huan and David B. Mitzi

    Article first published online: 26 NOV 2015 | DOI: 10.1002/aenm.201501609

    Fill factor (FF) losses are the second most significant barrier for Cu2ZnSn(SxSe1−x)4 (CZTSSe) solar cells, after the well-known open circuit voltage deficit (VOC,def). The sources of FF losses, in particular the series resistance in full bandgap-range CZTSSe, are investigated. CZTSSe with high S/(S + Se) ratios are found to develop nonohmic back contact at the CZTSSe/Mo interface.

  4. Nitrogen and Sulfur Codoped Graphite Foam as a Self-Supported Metal-Free Electrocatalytic Electrode for Water Oxidation

    Xiaowen Yu, Miao Zhang, Ji Chen, Yingru Li and Gaoquan Shi

    Article first published online: 25 NOV 2015 | DOI: 10.1002/aenm.201501492

    Nitrogen and sulfur codoped graphite foam (NSGF), prepared by oxidizing and doping a commercial graphite foil can be applied as a self-supported electrode without a current collector and polymeric binder for oxygen evolution reaction. Its electrocatalytic performance is superior or comparable to those of reported metal-free OER catalysts.

  5. Understanding Interface Engineering for High-Performance Fullerene/Perovskite Planar Heterojunction Solar Cells

    Yao Liu, Monojit Bag, Lawrence A. Renna, Zachariah A. Page, Paul Kim, Todd Emrick, D. Venkataraman and Thomas P. Russell

    Article first published online: 24 NOV 2015 | DOI: 10.1002/aenm.201501606

    Inverted planar heterojunction perovskite solar cells are optimized to achieve a maximum efficiency of 15.5% by inserting fulleropyrrolidine as an interface modification layer. The interface between silver electrode and electron transport layer is carefully examined using a variety of electrical and surface potential techniques. Interface engineering is critical for achieving high-performance perovskite solar cells.
