Pyranylidene/thienothiophene-based organic sensitizers for dye-sensitized solar cells 2019 Access copy available to the general public Unrestricted Novel push-pull systems featuring a 4H-pyranylidene donor fragment and thienothiophene as (part of) p-conjugated spacer have been synthesized in order to test their photovoltaic properties. An analogous derivative with two thiophene rings is also included in the study for comparison purposes. The optical and electrochemical properties of the novel D-p-A molecules have been discussed and DSSCs devices based on these dyes have been characterized. The photovoltaic performance is sensitive to the structural modification of the dye: the tert-butyl substituents on the pyranylidene moiety and the hexyl chains of the thienothiophene spacer were shown to improve the efficiency. A maximum power conversion efficiency of 6.41% has been achieved. info:eu-repo/grantAgreement/ES/DGA/E14-17R info:eu-repo/grantAgreement/ES/MINECO/CTQ2014-52331-R info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 4.613 2019 0.827 2019 CHEMISTRY, APPLIED 12 / 71 = 0.169 2019 Q1 T1 Chemical Engineering (miscellaneous) 2019 Q1 MATERIALS SCIENCE, TEXTILES 1 / 24 = 0.042 2019 Q1 T1 Process Chemistry and Technology 2019 Q2 ENGINEERING, CHEMICAL 26 / 143 = 0.182 2019 Q1 T1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Martínez de Baroja, N.
