Large scale modelling of photo-excitation processes in materials with application in organic photovoltaics
2019
La energía fotovoltaica a partir de materiales orgánicos representa una opción muy atractiva, en términos de costo y flexibilidad, para generar electricidad. Sin embargo, las bajas eficiencias alcanzadas hasta ahora limitan la producción de dispositivos fotovoltaicos a escala comercial. En el intento de superar las bajas eficiencias hoy en día se dedican considerables esfuerzos en la investigación y el diseño de materiales orgánicos así como de arquitecturas de dispositivos más eficientes. En particular esta tesis doctoral presenta un trabajo de carácter fundamental sobre los procesos de fotoexcitación en dispositivos optoelectrónicos orgánicos, donde se usan química teórica y modelización …
Strategies, Technologies and Novel Components for the Architectural Integration of Photovoltaics
2015
La ricerca riguarda l'integrazione architettonica del fotovoltaico (FV) per il retrofit energetico del patrimonio edilizio esistente e la costruzione di edifici a energia zero (ZEB). L'obiettivo è lo studio e la successiva definizione di strategie, tecnologie e componenti innovativi per l'involucro edilizio che integrino il fotovoltaico, con particolare attenzione verso le tecnologie fotovoltaiche di nuova generazione. Il lavoro si concentra anche sull'ottimizzazione energetica e sull'analisi delle prestazioni di un componente innovativo per il BIPV (Building Integrated Photovoltaics, letteralmente fotovoltaico integrato negli edifici) utile alla costruzione di involucri edilizi sostenibili…
State of the art and prospects for halide perovskite nanocrystals
2021
Financiado para publicación en acceso aberto: Universidade de Vigo/CISUG Metal-halide perovskites have rapidly emerged as one of the most promising materials of the 21st century, with many exciting properties and great potential for a broad range of applications, from photovoltaics to optoelectronics and photocatalysis. The ease with which metal-halide perovskites can be synthesized in the form of brightly luminescent colloidal nanocrystals, as well as their tunable and intriguing optical and electronic properties, has attracted researchers from different disciplines of science and technology. In the last few years, there has been a significant progress in the shape-controlled synthesis of …

An Economic Assessment of Micro-Scale Use of Renewable Energy Sources: Two Case Studies
2015
During recent times, renewable energy technologies have shown a relative fast growth in the global energy investment, global energy capacity and their integration within multiple sectors, particularly in the electricity sector. Renewable energy technologies have also experienced notorious declining costs on their manufacturing production. Nevertheless, while this growth is widely acknowledged, the share of renewables with respect total energy production has been moderate. Technological advancements in renewable energy have demonstrated the potential of renewables in energy generation and also that renewables can provide direct and indirect advantages over their counterparts. This thesis inv…
