DSSCs based on aniline derivatives functionalized with a tert-butyldimethylsilyl group and the effect of the p-spacer 2018 Access copy available to the general public Unrestricted We have developed four new dyes for DSSCs with a tert-butyldimethylsilylether in order to test their physical and photovoltaic properties. These dyes consist of a novel donor based on a functionalized N, N-dialkylaniline, a heteroaromatic p-conjugated spacer, such as thiophene or benzothiadiazole ring, and cyanoacetic acid as acceptor group. DFT theoretical studies predict, on the one hand, higher molar extinction coefficient for dyes with thiophene spacers than for those with benzothiadiazole groups while, on the other hand, the use of benzothiadiazole ring would give rise to the reduction of the back electron transfer (BET). The experimental studies have confirmed the predicted higher absorption of thiophene dyes and the better photovoltaic performance of the DSSCs prepared with these dyes. Finally, the stability of the response would support further studies of dyes with anilines functionalized with a tertbutyldimethylsilyl group to perform long-term devices. info:eu-repo/grantAgreement/ES/DGA/E07 info:eu-repo/grantAgreement/ES/DGA/E39 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/ 4.018 2018 CHEMISTRY, APPLIED 13 / 71 = 0.183 2018 Q1 T1 MATERIALS SCIENCE, TEXTILES 1 / 24 = 0.042 2018 Q1 T1 ENGINEERING, CHEMICAL 24 / 138 = 0.174 2018 Q1 T1 0.834 2018 Process Chemistry and Technology 2018 Q1 Chemical Engineering (miscellaneous) 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Colom, E.
