摘要
The juice extracted from pomegranate fruits containing cyanin (flavylium) is utilized as the light-harvesting analog in a dye sensitized solid-state photovoltaic cell. Strong chelation of flavylium with TiO2 changes it to quinonoidal form. A higher incident photon to current conversion efficiency is observed in solid-state TiO2 vertical bar pomegranate piment vertical bar CuI solar cell compare to that of the cells (TiO(2)vertical bar dye vertical bar CuI type) sensitized with other natural pigments.
