摘要
本文从生长在青藏高原的格桑花中提取天然色素,采用溶剂萃取和柱色谱法将格桑花色素分为A、B、C和D四种组分。研究了格桑花色素各组分的光、热性能,并组装了DSC。研究发现D组分色素光、热性能良好,主要成分为花色苷,其组装的DSC的光电转换效率为分离前色素组装的DSC的光电转换效率的2.03倍。
Natural dye was extracted from the garden cosmos in Qinghai-tibet. Garden cosmos dye was divided into four components,A,B,C and D. The stability of light and heat were studied. At the same time,dye sensitized solar cells( DSCs) were assembled. The study showed that the light and heat stability of D component was favourable and its main ingredient was cyanine. The cell photoelectric performance of D component was 2. 03 times better than the cell photoelectric performance of garden cosmos dye.
