    A new strategy to design dopant-free hole transport materials (HTMs) by modifying the organic molecule to include charged moieties that are accompanied by counter ions is investigated. The introduced counter ions are highly beneficial for improving the conductivity of the HTM and the perovskite solar cell devices based on the designed ionic HTM show impressive power conversion efficiency of more than 16%.

  3. Toward Enhanced Electronic and Ionic Conductivity in Olivine LiCoPO4 Thin Film Electrode Material for 5 V Lithium Batteries: Effect of LiCo2P3O10 Impurity Phase

    Gennady Cherkashinin, Sankaramangalam Ulhas Sharath and Wolfram Jaegermann

    Controlled off-stoichiometry is induced in 5 V olivine LiCoPO4 battery electrode material to overcome its insulating properties through the incorporation of lithium cobalt tripolyphosphate. An excellent electrochemical activity is achieved in this tailored carbon-free material. The electronic structure of the polyanionic compound, the Co2+/Co3+ redox energy, and quantification of the inductive effect are provided.

  4. Improving Perovskite Solar Cells: Insights From a Validated Device Model

    Tejas S. Sherkar, Cristina Momblona, Lidón Gil-Escrig, Henk J. Bolink and L. Jan Anton Koster

    Version of Record online: 21 FEB 2017 | DOI: 10.1002/aenm.201602432

    Thumbnail image of graphical abstract

    A numerical model is developed and validated that describes the operation of perovskite solar cells and quantitatively explains the role of contacts, the charge transport layers, charge generation, drift and diffusion of carriers and recombination. By doing so, a unique set of material parameters and physical processes is identified that describes these solar cells. To increase their performance, some guidelines are issued.

  5. Recent Advances in Perovskite Oxides as Electrode Materials for Nonaqueous Lithium–Oxygen Batteries

    Peng Tan, Meilin Liu, Zongping Shao and Meng Ni

    Version of Record online: 20 FEB 2017 | DOI: 10.1002/aenm.201602674

    Thumbnail image of graphical abstract

    Perovskite oxides as the electrode materials in nonaqueous lithium–oxygen batteries are reviewed. Future research directions of perovskite oxides should focus on the understanding of electrochemical mechanisms during the oxygen reduction and evolution processes, the structure design from nanoparticles to hierarchical porous structures, and the composite incorporation with improved electrical conductivities, catalytic activities, and structural merits.
