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. ... -
Effect of the bridge substitution on the efficiency of dye-sensitized solar cells
González Pedro, Victoria; Barea, Eva M; Langa, Fernando; De la Cruz, Pilar; Pelado, Beatriz Elsevier (2012-12)We have designed and synthesized a novel D–π–A dye based on zinc porphyrin as the donor, cyanoacrylic acid as the acceptor and trans-bis(3,4-ethylenedioxythiophene)vinylene as the bridge. Under standard global AM 1.5 solar ... -
Injection and Recombination in Dye-Sensitized Solar Cells with a Broadband Absorbance Metal-Free Sensitizer Based on Oligothienylvinylene
Caballero, Rubén; Barea, Eva M; Fabregat-Santiago, Francisco; De la Cruz, Pilar; Márquez, Lourdes; Langa, Fernando; Bisquert, Juan American Chemical Society (2008)A new metal-free sensitizer for improved light harvesting with dye-sensitized solar cells (DSC) has been synthesized and fully characterized. The molecular sensitizer was engineered by linking the tiophenes groups by methine ... -
Triplication of the photocurrent in dye solar cells by increasing the elongation of the π-conjugation in Zn-porphyrin sensitizers
Barea, Eva M; Caballero, Rubén; López Arroyo, Leticia; De la Cruz, Pilar; Langa, Fernando; Bisquert, Juan; Guerrero, Antonio Wiley-VCH Verlag Berlin (2011)Porphyrins are promising sensitizers for dye solar cells (DSCs) but narrow absorption bands at 400-450 and 500-650 nm limit their light-harvesting properties. Increasing elongation of the π-conjugation and loss of symmetry ...
