Combined Spectroscopic and TDDFT Study of Single-Double Anthocyanins for Application in Dye-Sensitized Solar Cell

New Journal of Chemistry (2018)

This research investigates single-double anthocyanins experimentally and theoretically for the first time. The natural donor contribution of methoxyl and glucose groups on anthocyanin dyes from cyanidin-3-glucoside (C3G) and peonidin-3-glucoside (P3G) was studied for dye-sensitized solar cell application. Single (C3G, P3G) and double (C3G+P3G) dyes were characterized by UV-Vis absorption spectroscopy, cyclic voltammetry, Fourier transform infrared, electrochemical impedance spectroscopy, including theoretical and experimental photochemical properties for final dye-sensitized solar cell (DSSC) application. All of the studied dyes show electron transfer and photo-energy conversion activities, with efficiencies up to 2.01% for combined C3G+P3G dye. The spectroscopy method combined with the computational analysis is applied in order to provide a better understanding on how the dye combination stabilizes the electronic structure, the electrons on C3G and P3G orbitals contribute to joining electron transfer, and to improving the performance of anthocyanin-based DSSC.
