	El objetivo de la tesis es el desarrollo de materiales y métodos de deposición de capas de perovskita utilizando procesos de alto vacío, principalmente mediante co-evaporación. Para la fabricación de los dispositivos, se han empleado y optimizado diferentes materiales transportadores de electrones y de huecos. La tesis está estructurada de la siguiente manera:Capítulo 1: se desarrolla un método de deposición novedoso para la preparación de capas delgadas de perovskitas mixtas iodo-bromo.Capítulo 2: se presenta el estudio de diferentes derivados del fullereno como materiales transportadores de electrones para conseguir células solares de perovskita de alta eficiencia.Capítulo 3: se optimiza la interfaz entre la capa transportadora de electrones y el electrodo metálico, con el objetivo de remplazar el bario cuya reactividad limita la estabilidad de los dispositivos.
	The aim of this thesis is the development of vacuum deposition methods for the fabrication of perovskite thin films, and their incorporation into devices using organic charge transport layers. The thesis will be structure as follows:Chapter 1: preparation of efficient single-junction perovskite solar cells with tunable bandgap using vacuum processed techniques.Chapter 2: study the effect of different fullerene derivatives as electron transport materials on the performance of perovskite solar cells. Additionally, the interface between the fullerene and the perovskite is optimized, in order to reduce the non-radiative recombination and maximize the photovoltage.Chapter 3: Interface engineering towards stable electron transport materials. Development of a new electrode buffer layer as an alternative to reactive metal cathodes in p-i-n perovskite solar cells....
