Single junction and tandem perovskite solar cells
2017
En este trabajo hemos estudiado diferentes métodos para preparar dispositivos fotovoltaicos de perovskitas. Se han cumplido los tres objetivos definidos al inicio de este periodo de investigación: 1. Hemos establecido con éxito un método estable y reproducible para la fabricación de células solares de perovskita procesadas desde disolución, empleando acetato de plomo y MAI como materiales precursores. 2. Hemos conseguido sintonizar el "bandgap" de perovskitas mixtas de bromuro y yoduro para alcanzar un valor de 2.0 eV, aprovechando las propiedades estabilizadoras de los cationes Cs+ y FA. Hemos investigado perovskitas de doble halogenuro y doble catión Cs0.15FA0.85Pb(Br0.7I0.3)3, fabricadas…
Effects of steric encumbrance of iridium( iii ) complex core on performance of solution-processed organic light emitting diodes
2020
Iridium(iii) complexes are the most frequently applied commercialized green and red emitters for organic light emitting diode (OLED) displays. Throughout years a significant research effort has been devoted to modify these compounds, in order to make them suitable for cost-effective solution-processing techniques, such as inkjet printing. To achieve this, the inherent tendency of the complex molecules to form poorly emissive aggregates needs to be suppressed. In many cases this has been achieved by an encapsulation of the iridium(iii) complex core with dendritic structures, composed of either passive or charge-transporting fragments. In order to validate this approach, we acquired three str…
