摘要
Dye-sensitized solar cells (DSSCs) were assembled using natural dyes extracted from red cabbage as a sensitizer. In this work, we investigated the adsorption characteristics and the electrochemical behavior for harvesting sunlight and electron transfer in red cabbage DSSCs under different solvents and pH. For the red cabbage dye-sensitized electrode adsorbed at pH 3.5, the solar cell yields a short-circuit current density (J(sc)) of 1.60 mA/cm(2), a photovoltage (V-oc) of 0.46 V, and a fill factor of 0.55, corresponding to an energy conversion efficiency (eta) of 0.41%.
