Improving device lifetime and stability remains the stumbling block of commercialization hybrid perovskite-based devices (HPDs). Although extensive efforts have been paid, thermal property, one most crucial parameters in conventional solid-state electronic devices, has rarely studied for HPDs. Here, we investigate temperature-dependent ultralow conductivity ultrahigh expansion single-crystalline MAPbX3 (MA = CH3NH3), which are found distinct from traditional thin-film solar cells materials....
The crystal structures, elastic, anisotropy, and optical properties of zero-dimension perovskite Cs4BX6 (B = Pb, Sn; X Cl, Br, I) compounds are investigated by first-principles calculations. moduli become lower in accordance with the order I, tin-based larger than lead-based compounds. These two rules apply to other halide perovskites. Besides, present obvious mechanical anisotropy poor ductility. For properties, alignment PbX6 octahedra dictates transition behavior materials pure candidates...

Halide perovskite semiconductors exhibit ultralow thermal conductivities, making them potentially suitable for thermoelectric applications. Nevertheless, the properties of prototypical halide CH3NH3PbI3 have been limited with a very low dimensionless figure merit (ZT) and narrow operating temperature window, which are attributed to its poor electronic conductivity unstable hybrid organic–inorganic composition, respectively. Here, we report bulk synthesis stable, all-inorganic CsSn0.8Ge0.2I3...
The newly functional polymeric semiconductor materials, mesoporous graphitic carbon nitride (g-C3N4), have been synthesized by using a general and efficient sol–gel synthetic approach. By means of transmission electron microscopy (TEM), we accomplished systematic analysis on the morphology changes final formation g-C3N4 product during whole synthesis process. Our results indicate that method is simple, viable technique to large-scale production materials. This proposed also allows controlled...
Abstract Considerable research efforts have been devoted to develop noble‐metal‐free cocatalysts coupled with semiconductors for highly efficient photocatalytic H 2 evolution as part of the challenge toward solar‐to‐fuel conversion. Herein, a new cocatalyst excellent activity in electrocatalytic reaction (HER) that is based on Co sheathed N‐doped graphitic carbon nanosheets (Co@NC) was fabricated by surfactant‐assisted pyrolysis approach and then g‐C 3 N 4 construct D‐2 D /Co@NC composite...
