In stead of ruthenium dyes, organic dye cocktails which contain two commercial cheap organic dyes — i.e. TCPP /Mercurochrome and C343/Mercurochrome — with various compositions were employed to sensitize the solar cell in this study. Adsorption properties, adsorption dynamics and dye loading, dye aggregation behavior, and photosensitization properties were investigated systematically. The experimental results indicated that dye cocktails were efficient in light harvesting. Furthermore, co-adsorption was found to suppress the aggregation of dyes. The overall efficiencies, however, show a negative deviation from the ideal mixing calculations. The main factors that affect the sensitization performance were discussed further through dye loading and IPCE(incident photon-to-electron conversion efficiency) characteristics.
