| الوصف: | Novel push-pull systems featuring a 4H-pyranylidene donor fragment and thienothiophene as (part of) π-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-π-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. ; Financial support from MINECO (CTQ2014-52331R) and Gobierno de Aragón-FEDER-Fondo Social Europeo 2014–2020 (E14_17R) is gratefully acknowledged. A predoctoral fellowship to A. B. Marco (FPI BES–2009–016966) is also acknowledged. ; Peer reviewed |
