摘　　要：通过萃取西藏林芝核桃果皮、江孜沙棘果实以及拉萨紫草根部的天然色素,分析研究了西藏天然色素光吸收性能;利用以上3种天然色素以及它们的混合色素,研制了染料敏化太阳能电池。结果表明,核桃与紫草的混合色素(TiO2薄膜多层)DSSC电池效率最高,达到8.2%。The absorption properties for the Tibetan natural pigments,which were extracted from Linzhi walnut peels,Gyantse sea buckthorn fruits and Lhasa comfrey roots were studied.With the above three natural pigments and their mixtures,the dye-sensitized solar cells were developed.The results show that maximum efficiency of 8.2% has been achieved for a pigments mixture of walnut and comfrey （TiO2 thin film multilayer） DSSC.
