从青藏高原同一海拔的4种植物——菠菜、金莲花、喇叭花和格桑花中,分别提取天然色素,并且组装成染料敏化太阳能电池.对4种植物色素的光学性能,以及格桑花色素和菠菜色素组装的电池的性能进行了研究.研究发现,菠菜色素在300～500 nm和610～700nm之间以及格桑花色素在300～400nm和480～600nm之间有较好的吸收峰,但格桑花色素组装的电池的光电转换效率却是菠菜色素组装的电池的2.55倍.进一步研究发现,格桑花色素在TiO2薄膜上的吸附方式为化学吸附,而菠菜色素为物理吸附,格桑花色素的主要成分为花青素.最后,对格桑花色素的光、热稳定性进行研究,发现其热稳定性良好,光照后吸光度值略有下降.
