2023年9月25日 · Two-dimensional X-ray diffraction (2D-XRD, Bruker D8 Discover, Cu Kα) was performed with an incident angle of 5° to analyze the crystallinity and orientation within the PVK films.

2023年2月28日 · To elucidate the role of buried Py on the crystallinity and morphology of PVK films, SEM and XRD characterization were conducted. Fig. 3a shows the cross-sectional SEM image of the PSC, and the result show that PVK has an ideal thickness (∼480 nm) that contributes to the full utilization of light.

th nano-crystalline titanium oxide (TiO2) were fabricated by using bath deposition method. The X-ray diffraction (XRD) data revealed th. amorphous nature of PVK polymer matrix and increased with increase of TiO2 concentration. The complexatio.

The layers structure and morphology were assessed by X-ray diffraction (XRD) and scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM/EDX).

2015年3月5日 · It was found that particle size of AgNPs prepared by laser ablation can be controlled by experimental condition chosen. XRD, TEM and PL indicated the complexation between AgNPs and PVK in the nanocomposite system. XRD spectra and the band tail values confirm the enhancement of crystallinity of such system.

高度取向的 PVK (100) 在产量和寿命方面表现出改善的光致发光。 此外，通过 KPFM 测量的高取向 PVK 的接触电位差 (CPD) 的高空间分辨率映射显示出比非取向 PVK 更均匀的表面电位分布。

For CsPbBr3 perovskite materials, it is especially important to reduce interface defects, suppress non-radiative recombination, and improve morphology to achieve highly efficient and stable CsPbBr3...

2024年10月23日 · 此外，X射线衍射光谱 (XRD)中PVK (100)面 (14.0°)峰值增强和CIGS峰值的减弱，也验证CIGS基板上膜质量和覆盖率的提高 (图2c)。 随后，添加剂对PVK成核和结晶过程的影响通过XRD分析进一步被验证 (图2d)。

2023年6月13日 · Multiple-source thermal evaporation is emerging as an excellent technique to obtain perovskite (PVK) materials for solar cell applications due to its solvent-free processing, accurate control of stoichiometric ratio, and potential for scalability.

2023年10月3日 · Based on XRD analyses, Pvk + Bi + Mo and Pvk + Bi + Ag exhibited better thermal stability than Pvk + Ag. To further identify the potential chemical reactions between the metal electrodes and the Pvk films, the Pvk + Bi + Ag …
