通过将紫苏叶提取物中的颜料涂覆在 TiO2 纳米晶薄膜上并随后沉积 p-CuI 制成的染料敏化太阳能电池的能量转换效率约为 1.3%。从细胞的光电流作用光谱可以看出，紫草素和叶绿素都有助于光能收集。这是从单一自然资源中提取的染料混合物协同敏化的第一个成功例子。评论了这种性质的研究在理解多种色素在光合作用中的作用和拓宽染料敏化装置的光谱响应方面的有用性，也表明了该实验的教学价值。 (c) 2005 Elsevier B.V. 保留所有权利。
A dye-sensitized solar cell made by coating pigments in an extract from shiso leaves on a nanocrystalline film of TiO2 and subsequent deposition of p-CuI is found to have an energy conversion efficiency of similar to 1.3%. Both shisonin and chlorophyll contribute to light energy harvesting as seen from the photocurrent action spectrum of the cell. This is the first successful example of synergistic sensitization by dye cocktail extracted from a single natural resource. The usefulness of studies of this nature in understanding the role of multiple pigments in photosynthesis and broadening of the spectral response of dye-sensitized devices is commented, indicating also the pedagogic value of the experiment.
