文摘

DSSC were sensitized with purified anthocyanins extracted following a very simple path from the red flowers of Erythrina crista-galli, the national flower from Uruguay and Argentina 0.73 % conversion efficiency values were obtained Performance differences between extracted anthocyanins obtained in presence and absence of protons were clearly observed, whereas slightly differences in the polarity of the solvents do not show conclusive results. Measured conversion efficiency values are situated among larger reported ones when using anthocyanins as sensitizers Anthocyanins from ceibo’s flower show a ΦF ~ 0.001, in both in water and ethanol solutions
