Enhance and Performance Evolution of Silver-Doped Titanium Dioxide Dye-Sensitized Solar Cells Using Different Dyes

In this study, silver was used to doped TiO۲ with Azadirachtaindica (neem), Annonamuricata (Soursop leaf), Manihotesculenta (cassava leaf), and Myrianthus arboreus (Coat button leaf) for DSSCs fabrication. The sensitized TiO۲/silver with dye recorded an efficiency of ۰.۴۹%, ۰.۰۳%, ۰.۰۵%, and ۰.۲۲% for Azadirachtaindica (neem), Annonamuricata (Soursop leaf), Manihotesculenta (cassava leaf), and Myrianthus arboreus (Coat button leaf) respectively. The optical energy bandgap was observed to be ۲.۳۲ eV for TiO۲ and ۲.۵۲ eV, ۲.۳۱ eV, ۲.۴۹ eV, and ۲.۵۱ eV for Neem, Soursop Cassava, and Coat button leaf dye. The structure of the cells is polycrystalline with a most outstanding peak at ۲ theta angles of ۳۰.۳۷۵ o and ۳۰.۴۶۴ o corresponding to (۲۰۰) therefore, secondary peaks were noticed at ۲ theta angles of ۲۴.۸۹۱ °, ۲۷.۵۰۹ o, ۳۲.۹۱۵ o, ۲۷.۵۰۹ o, ۳۵.۲۹۶ o, ۳۸.۸۱۴ o, ۴۳.۱۵۲ o, ۴۷.۵۷۹ o, ۵۳.۲۳۱ o and ۵۹.۱۳۰ o for TiO۲ and ۲۶.۱۱۶ °, ۲۷.۸۳۵ o, ۳۲.۶۶۷ o, ۳۶.۱۹۵ o, ۳۹.۸۰۲ o, ۴۱.۹۲۶ o, ۴۷.۱۷۳ o, ۵۲.۰۸۴ o, and ۵۸.۱۵۲ o for TiO۲/Ag۰.۱/Neem leaf, TiO۲/Ag۰.۱/soursop leaf, and TiO۲/Ag۰.۱/cassava leaf which corresponds to (۱۰۱), (۰۰۴), (۱۰۵), (۲۱۱), (۲۰۴), (۱۱۶), (۲۲۰), and (۲۱۵) and (۳۰۳) subsequently
