2020年3月1日 · XRD scans revealed a semicrystalline nature of polymer composite, which is characterized by two broad bands at 2θ ≈19 and 23° and showed an increase in the amorphous regions with increasing CsBr. The values of the energy gap were reduced with a continuous increase in the filling level of CsBr due to charge transfer complexes (CTCs) between ...

2021年3月9日 · In this work, we develop a low-temperature crystallization strategy to grow CsPbBr 3 perovskite single crystals in water. Then, we carefully investigate the structure and optoelectronic properties...

At the optimal CsBr concentration (0.5 M), the corresponding solar cell achieves a power conversion efficiency of 10.92%. This work provides an effective way to stabilize the cubic CsPbI 3– x Br x ( x < 1) phase at low temperature to further improve the performance of all-inorganic perovskite solar cells.

2024年6月15日 · In this work, a facile CsBr intercalated nanostructured intermediate based two-step method is reported for simultaneously achieving good morphology and pure phase of CsPbBr 3 films. With the CsBr intercalation, the intermediate films deposited in the first step exhibit porous nanostructure and Cs x Pb 2 Br 4+x crystal phase.

2023年2月1日 · X-ray diffraction (XRD) and energy dispersive X-ray (EDX) measurements were employed to examine the relationship between the precursor ratio and Cs 3 Bi 2 Br 9 phase formation. Field emission scanning electron microscopy (FESEM) was used to investigate the morphology of the synthesized materials.

2016年11月21日 · In this work, we present a simple and fast route to solution growth of CsPbBr 3 SCs using the ITC method, under ambient atmosphere and using low-cost precursors. Obtained SCs can be handled in air and can be easily wet-polished using DMSO; all such treatments showed no substantial effect on the electric properties of SCs.

2024年5月11日 · Combining grazing incidence wide-angle X-ray scattering (GIWAXS) and grazing incidence X-ray diffraction (GIXRD) measurements, we have further analyzed the structural details of CsPbBr 3 and DBSA...

CsI, CsBr and GaAs thin films have been grown by pulsed laser deposition on glass substrates. The morphology and structure of the films have been studied using X-ray diffraction and scanning...
