Influence of illumination spectra on DSSC performance

In this study the effect of the illumination spectra on the energy-conversion efficiency was investigated. DSSCs built using anthocyanin dyes were illuminated by a halogen lamp and an LED lamp with color temperatures of 3000 K and 5000 K, respectively, in combination with color filters or without them. Depending on the illumination spectra, the efficiency of the cell was found to vary between 0.06% and 0.33%, pointing out the importance of tailoring the DSSCs for the planned application.
