In article number 1600256, Min Zhu and co-workers present the construction of a hierarchical Fe3O4@polypyrrole nanocage anode for Li-ion batteries via a facile reduction and in-situ polymerization route. This advanced anode design can enhance battery performance by providing sufficient space for large volumetric expansion, short ion diffusion in electrodes, large surface area, and high electrode stability.
Semi-Transparent Solar Cells
With ever-increasing demand for electrical energy consumption, semi-transparent solar cell (ST-SC) technology is desired to be integrated seamlessly onto the windows of buildings or vehicles. In article number 1502466, Nam-Gyu Park, Seunghyup Yoo, and co-workers demonstrate high-performance ST-SCs with excellent thermal-mirror functionality using methylammonium lead iodide perovskite photoactive layers and metal-based transparent electrode capped with high-index dielectric layers.
