  1. Highly Active and Stable Graphene Tubes Decorated with FeCoNi Alloy Nanoparticles via a Template-Free Graphitization for Bifunctional Oxygen Reduction and Evolution

    Shiva Gupta, Liang Qiao, Shuai Zhao, Hui Xu, Ye Lin, Surya V. Devaguptapu, Xianliang Wang, Mark T. Swihart and Gang Wu

    A new type of ultralarge diameter graphene tubes(up to 1000 nm)linked with in situ formed FeCoNi alloy nanoparticles is prepared via one-step template-free graphitization of low-cost dicyandiamide. The novel carbon-tube based catalyst demonstrates excellent activity and sufficient stability for bifunctional oxygen reduction and oxygen evolution reaction catalysis in alkaline media.

    Carbon nanotubes are utilized in thin-film solar cells as absorbers, interfacial layers, and electrodes due to their exceptional chemical and optoelectronic properties. Recent efforts to isolate carbon nanotubes with desired properties and use them to increase performance, near-infrared absorption, and stability in organic, perovskite, and transition metal dichalcogenide thin-film solar cells are highlighted.

  3. Reduced Recombination in High Efficiency Molecular Nematic Liquid Crystalline: Fullerene Solar Cells

    A detailed study of bimolecular recombination in a high efficiency organic solar cell, comprised of a liquid crystalline donor and PC71BM, is presented. Using multiple techniques, it is shown that the bimolecular recombination is nearly 150 times suppressed with respect to that predicted by Langevin theory. This reduction is attributed to an equilibrium between charge transfer states and free charges.

  4. Trade-Off between Trap Filling, Trap Creation, and Charge Recombination Results in Performance Increase at Ultralow Doping Levels in Bulk Heterojunction Solar Cells

    Ultralow level doping (≈ppm) can increase the power conversion efficiency of organic solar cells. Trap states filling by free charges and trap creation by dopant ions have competing effects on carrier mobility and open circuit voltage thereby imposing constraints on the effectiveness of doping. Measurements are performed to study what electronic process dominates in different materials or fabrication conditions.

  5. Compositionally Graded Cathode Material with Long-Term Cycling Stability for Electric Vehicles Application

    Al substituted compositionally graded NCM cathode (Al-FCG61) shows its improved cycle life because Al-substitution in NCM FCG61 cathode strengthens the grain boundaries, and thereby delays the nucleation of microcracks. The Al-FCG61 cathodes are cycled at 100% depth of discharge for 3000 cycles showing capacity retention of 84% to fully use their available capacity and subsequent reduction of battery cost.
