Chen P Yum JH De Angelis F Mosconi E Fantacci S Moon SJ Baker RH Ko J Nazeeruddin MK Grätzel M 2009 Solid-state dye-sensitized solar cells were fabricated using an organic dye, 2-cyanoacrylic acid-4-(bis-dimethylfluoreneaniline)dithiophene (JK2), which exhibits more than 1 V open-circuit potential (V(oc)). To scrutinize the origin of high voltage in these cells, transient V(oc) decay measurements and density functional theroy calculations of the interacting dye/semiconductor surface were performed. A negative conduction band shift was observed due to the favorable dipolar field exerted by the JK2 sensitizer to the TiO(2) surface, at variance with heteroleptic Ru(II)-dyes for which an opposite dipole effect was found, providing an increased V(oc). https://sonar.ch/global/documents/180643 eng info:eu-repo/semantics/altIdentifier/doi/10.1021/nl901246g info:eu-repo/semantics/altIdentifier/pmid/19438193 Nano letters. - 2009 High open-circuit voltage solid-state dye-sensitized solar cells with organic dye. http://purl.org/coar/resource_type/c_6501
