Abstract
In this work, the dying process of the cells was taken into focus. The aim was to check several natural dyes for their suitability in DSSCs. The premise for the choice of dyes was that they had to be cost-efficient, i.e. not purified in chemical processes, and non-toxic. The outcome shows that the cells which were dyed with a dye of the group of anthocyanins, such as forest-fruit tea or maqui-berry extract, had the best efficiencies. Additionally, the dying times and dye concentrations were found to influence the DSSC performance in an unexpected way, with higher concentrations necessitating longer dying durations.
