Energy issues have taken on considerable importance in our daily lives. They have to address the dual issue of the expanding energy demand as well as environmental and ecological concerns. Although, fossil fuels have undeniable advantages, their drawbacks are constantly driving the search for alternative solutions. In this regard, eco-friendly and effective materials are always being investigated for the development of energy storage capacitors and electrocaloric (EC) refrigeration devices. Additionally, the context of miniaturization requires the fabrication of smaller and smaller material sizes, ranging from ceramics to dense and continuous (2D) thin films to nanostructured (1D) thin films exhibiting hierarchical structures. The goal of this thesis is to understand how the dimensionality, architecture, geometry, and grain orientation of the ceramics and thin films intend to enhance the electrocaloric effect and stored energy density of these materials. By using two synthesis techniques: sol-gel (SG) and electrospinning (ES), we first synthesized BCZT ceramics (BCZT-SG and BCZT-ES) which underwent a sintering time optimization process. Then, the bulk ceramics were subjected to studies in order to evaluate how the synthesis technique and sintering time influenced the dielectric, electrocaloric, and energy-storage properties of BCZT ceramics. The physico-chemical characterisations revealed that on the one hand, BCZT ceramics sintered for 6h had improved microstructural, dielectric, electrocaloric and energy storage properties, on the other hand, the ceramics prepared by the electrospinning method (BCZT-ES) are more efficient than those prepared by the sol-gel process (BCZT-ES) which could be attributed to the fineness of the grains of the BCZT-ES powders and to the significant ratio of the coexisting tetragonal (T) and orthorhombic (O) phases in ceramics.. Indeed, the BCZT-ES-6h ceramic showed an interesting recovered energy density of 233.69 mJ/cm3 and a high energy efficiency of 72.17% at E = 40 kV/cm, around the ferroelectric-paraelectric transition. Thus, this ceramic shows an electrocaloric coefficient reaching high value of ζ ≈ 0.523 K.mm/kV. Instead of using ceramic, using BCZT thin layers produced using the sol-gel process coupled with the spin coating technique, allowed us to apply higher electric fields, which promoted interesting energy storage properties. For these BCZT thin films, experimental parameters (binder, mode and temperature annealing) were optimized. the BCZT-850 film crystallises in a pure perovskite phase with relatively dense granular microstructure. It exhibits a high value of Wr = 1.211 J/cm3 with an interesting energy efficiency of 72.31% at an applied field of 372 kV/cm. In addition, a hydrothermal synthesis of vertically aligned (1D) nanostructured BaTiO3 (BT) films was conducted to better understand the effect of grain shape and orientation on the dielectric properties of thin films. The optimal conditions for the synthesis of these types of films were established by a methodical analysis of the various hydrothermal synthesis parameters. A 1D BaTiO3 lattice with nanorods preferentially aligned along the c-axis exhibiting a high aspect ratio of ≈ 9.27, and a very high dielectric constant of ≈ 16539 were produced by using the optimal parameters
