Abstract

In this study, anthocyanins (A), betalain (B), and chlorophyll (C) were extracted from natural sources. Each dye was combined (volume ratios of 1:1) and labeled AB, AC, BC, and ABC. The ABC dyes were incorporated with AgNO3 in various concentrations to improve the photovoltaic performance. The optical properties of the prepared dyes, the morphology of the TiO2 layers containing the prepared dyes, and the photovoltaic performance of developed DSSCs were evaluated. The results revealed that fabricated DSSCs composing ABC incorporated with 3 mM AgNO3 yielded the best conversion efficiency as doping can induce faster electron transport. It demonstrated that AgNO3-incorporated ABC, with the lowest Ag concentration, was the best dye modification to produce with an efficiency of 1.635 %. This is because Ag has good conductivity properties, so the higher concentration added may increase the conductivity of the TiO2..
