An unconventional helical push-pull system for solar cells / D. Dova, S. Cauteruccio, N. Manfredi, S. Prager, A. Dreuw, S. Arnaboldi, P.R. Mussini, E. Licandro, A. Abbotto. - In: DYES AND PIGMENTS. - ISSN 0143-7208. - 161(2019 Feb), pp. 382-388.
Abstract:
The synthesis, photophysical and electrochemical characterization, theoretical calculations and photovoltaic
studies of a push-pull dye with an unconventional nonplanar tetrathiahelicene π−spacer between the donoracceptor
groups, are reported. The molecule exhibits suitable HOMO LUMO levels to be used in DSSC. The
presence of the donor-acceptor helical architecture allows the internal charge transfer and subsequent electron
injection to the conduction band of TiO2 leading to the good photocurrent value of 4.6 mA cm−2..
