Resumen
En el presente trabajo de tesis se contribuyó con el desarrollo de nuevos materiales fotovoltaicos para ser usados en celdas solares de bajo costo y bajo impacto ambiental. En particular se contribuyó en aspectos relacionados con estudio de propiedades ópticas, eléctricas y morfológicas de películas delgadas del compuesto hibrido orgánico/inorgánico CH3NH3PbI3 (MAPI) con estructura tipo perovskita, depositadas por evaporación, para ser usadas como capa activa en celdas solares híbridas que están siendo intensivamente investigadas a nivel mundial. Especial énfasis fue puesto al estudio de propiedades de transporte eléctrico en las interfaces de celdas solares híbridas con estructura FTO/ZnO/CH3NH3PbI3/P3HT/Au, usando la técnica de espectroscopia de Impedancia. Adicionalmente, se evaluó el desempeño de la celda solar tipo perovskita, de donde se obtuvieron eficiencias máximas de 7,5%.
Abstract: In this thesis work, it was contributed with the development of new photovoltaic materials to be used in low cost solar cells and low environmental impact. In particular, it was contributed to aspects related to the study of optical, electrical and morphological properties of thin films of organic / inorganic compound CH3NH3PbI3 (MAPI) with perovskite-like structure, deposited by evaporation, to be used as an active layer in hybrid solar cells that are being intensively researched worldwide. Special emphasis was placed on the study of electric transport properties in the hybrid solar cell interfaces with structure FTO/ZnO/CH3NH3PbI3/ P3HT/Au, using the impedance spectroscopy technique. Additionally, the performance of the perovskite-type solar cell was evaluated, from which maximum efficiencies of 7.5 % was obtained.
