A star-shaped sensitizer based on thienylenevinylene for dye-sensitized solar cells
Urbani, Maxence; Barea, Eva M; Trevisan, Roberto; Aljarilla, Ana; De la Cruz, Pilar; Bisquert, Juan; Langa, Fernando Elsevier (2013-01)A novel star-shaped dye based on highly conjugated oligothienylenevinylene (nTV) bearing pendant solubilizing hexyl chains and end-capped with three tetramethylammonium cyanoacetates as anchoring groups has been synthetized. ... -
Carrier density and interfacial kinetics of mesoporous TiO2 in aqueous electrolyte determined by impedance spectroscopy
Gimenez, Sixto; Dunn, Halina K.; Rodenas, Pau; Fabregat-Santiago, Francisco; Miralles, Sara G.; Barea, Eva M; Trevisan, Roberto; Guerrero, Antonio; Bisquert, Juan Elsevier (2012)Water splitting at a semiconductor/solution interface with the only input of sunlight to generate hydrogen is one of the most attractive strategies to produce and store chemical energy. In the present study we have ... -
Harnessing infrared photons for photoelectrochemical hydrogen generation. A PbS quantum dot based "quasi-artificial leaf"
Trevisan, Roberto; Rodenas, Pau; González Pedro, Victoria; Sima, Cornelia; S. Sánchez, Rafael; Barea, Eva M; Mora-Sero, Ivan; Fabregat-Santiago, Francisco; Gimenez, Sixto American Chemical Society (2013)Hydrogen generation by using quantum dot (QD) based heterostructures has emerged as a promising strategy to develop artificial photosynthesis devices. In the present study, we sensitize mesoporous TiO2 electrodes with ... -
PEDOT nanotube arrays as high performing counter electrodes for dye sensitized solar cells: study of the interactions among electrolytes and counter electrodes
Trevisan, Roberto; Döbbelin, Markus; Pérez Boix, Pablo; Barea, Eva M; Tena-Zaera, Ramón; Mora-Sero, Ivan; Bisquert, Juan Wiley (2011-10)PEDOT nanotube arrays present a better catalytic activity with I−/I3− redox than standard platinized counter electrodes used for dye sensitized solar cells exhibiting thereby a photoconversion efficiency as high as 8.3%. ...
