The Dye-Sensitized Solar Cell (DSSC) is still inefficient. Because low efficiency is caused by electron recombination, this study reduced it by the electrodeposition of Ag metal against TiO2. XRD was used to determine the crystal structure, size, and effect of Ag electrodeposition on TiO2. SEM-EDS was used to investigate the surface morphology and the presence of Ag metal in the TiO2-Ag layer. Anthocyanins were used as dyes. To improve thermal stability and achieve a bathochromic effect, the anthocyanin used was co-pigmented with salicylic acid. The anthocyanin extract used in this study was obtained from the red grape peel (Vitis Vinifera), jengkol peel (Pithecellobium jiringa), senduduk fruit (Melastoma malabathricum L), and mangosteen peel (Garcinia Mangostana L). The dyes were identified using UV-Vis and FTIR. The electrical properties of the resulting DSSC were measured using a multi-meter. According to this study, the electrodeposition of Ag on the TiO2 layer could improve DSSC efficiency. The highest efficiency was achieved in DSSC with TiO2-Ag and co-pigmented dye using mangosteen peel as the dye source
