Thermal And Structural Study Of A Perovskite Layer [NH3 (CH2)3 - COOH] CdCl4

In this paper we present a study of a Phase Change Material type Perovskite Layerwhich have solid-solid transitions and thermal properties suitable for Thermal EnergyStorage. Structural study shows that organic chain in this organic-inorganic compoundpresents “trans” and “gauche” conformations due to the acid function. DSC studyshows three transitions with the increasing of temperature due to the change ofconformations in the organic chain.PCM, TES, Perovskite Layer, phase transitions, conformations, DSC

Synthesis And Characterization Of New Materials Like Perovskite [NH3-(CH2)n-NH3] ZnCl4 avec n=8 et 10

During this work, we have prepared new semiconductors [NH3-(CH2)n-NH3]ZnCl4 (n=8 ; 10) (Short notation 2CnZnCl4) which are self assembled organic-inorganic hybrid materials by solution chemistry technique using the HCl in evaporating phase. The grown crystals have been studied by infrared absorption spectroscopy, X-ray diffraction, scanning electron microscopy; the electrical properties of the hybrid perovskites synthesised were also studied by UV-visible measurements.
