    Vacuum-sublimed inorganic cesium lead halide perovskite thin films are prepared and integrated in all-vacuum-deposited solar cells. Special care is taken to determine the stoichiometric balance of the sublimation precursors, which has great influence on the device performance. The mixed halide devices exhibit exceptional stabilized power conversion efficiency (11.8%) and promising thermal and long-term stabilities.

  2. Metal–CO2 Batteries on the Road: CO2 from Contamination Gas to Energy Source

    A room-temperature perovskite material yielding a power conversion efficiency of 18.1% (stabilized at 17.7%) is demonstrated by judicious selection of cations. Both cesium and methylammonium are necessary for room-temperature formamidinium-based perovskite to obtain the photoactive crystalline perovskite phase and high-quality crystals. This room-temperature-made perovskite material shows great potential for low-cost, large-scale manufacturing such as roll-to-roll process.

  4. Porous One-Dimensional Nanomaterials: Design, Fabrication and Applications in Electrochemical Energy Storage

    Qiulong Wei, Fangyu Xiong, Shuangshuang Tan, Lei Huang, Esther H. Lan, Bruce Dunn and Liqiang Mai

    Porous 1D nanomaterials utilize the advantages of both 1D nanoarchitecture and porous morphology to further enhance the performance of materials for energy storage applications. Here, the current status of porous 1D nanostructures, from methodologies for rational and controllable synthesis, to their successful application in lithium-ion batteries, sodium-ion batteries, lithium-sulfur batteries, lithium-oxygen batteries and supercapacitors is presented.

  5. Roll-to-Roll Production of Metal-Organic Framework Coatings for Particulate Matter Removal

    A powerful roll-to-roll hot-pressing strategy for mass production of metal-organic framework (MOF)-based filters (MOFilters) using various MOF systems with ranges of substrates is presented. Thus-obtained MOFilters show superior particulate matter removal efficiency under desired working temperatures. Such versatile MOFilters can be scaled up and purposely designed which endow MOFilters with great potentials in both residential and industrial pollution control.
