The low power conversion efficiency (PCE) of hole transport materials (HTM) – free carbon‐based perovskite solar cells (C‐PSCs) poses a challenge. Here, a novel 2D Eu‐TCPP MOF (TCPP; [tetrakis (4‐carboxyphenyl) porphyrin]) sandwiched between the perovskite layer and the carbon electrode is used to realize an effective and stable HTM‐free C‐PSCs. Relying on the synergistic effect of both the metal‐free...
Tungsten doped indium oxide (IWO) thin films were deposited on glass substrate at room temperature by radio frequency reactive magnetron sputtering. Chemical states analysis was carried out, indicating that valence states of element W in the films were W 4+ and W 6+ . The effects of sputtering power and film thickness on the surface morphology, optical and electrical properties of...
This paper presents the branch aircraft's digital assembly process design and simulation system, and illustrates the key technologies and characteristic of digital assembly process design and simulation. Take advantage of these technologies, branch aircraft's assembly process is designed successfully by computer in virtual environment.
