dc.description.abstract Through the end of contribute to the next generation of photovoltaics and light emitting devices the preparation of no-expensive and high quality materials with high PLQY and reduced non-radiative recombination is crucial. For such a reason the thesis is focus on the develop of high optoelectronic potential hybrid perovskite material and on their processing methods. In the different Chapters, various low dimensional perovskite synthetic approaches and their application are investigated. In the Chapter 2, a low dimension quasi-2D perovskite with a remarkable PLQY was prepared thanks to interplay of different fabrication approaches such us altered stoichiometry, solution engineered deposition and the use of electron donor passivating agent. In the Chapter 3, quasi-2D and pure 2D perovskite were fabricated by vacuum-deposition method in order to overcame the limitation of the solution process approach. High crystallinity, homogenous, compact films were prepared. However, different challenges were face up during the deposition process. In the Chapter 4, the 2D perovskites fabricated by dual-source vacuum deposition in the Chapter 3 were apply to study the effect and the advantages of a wide bandgap 2D perovskite material on the reduction of non-radiative recombination of a polycrystalline 3D perovskite in a heterostructure system. es_ES
