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 the theoretical and experimental photochemical properties for final dye-sensitized solar cell (DSSC) applications. All of the studied dyes show electron transfer and photo-energy conversion activities, with efficiencies up to 2.01% for the combined C3G + P3G dye. The spectroscopy method combined with the computational analysis is applied in order to provide a better understanding of how the dye combination stabilizes the electronic structure, the electrons on the C3G and P3G orbitals contribute to the joining electron transfer, and to improving the performance of the anthocyanin-based DSSC.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This work was supported by the Program Penelitian Kerjasama Luar Negeri, Publikasi Internasional, and WCP Program research grant by the Ministry of Research, Technology and Higher Education, Republic of Indonesia.
