Abstract

A Dye-sensitized solar cells were fabricated using anthocyanin dyes extracted from frozen blueberry using the column chromatography method. To determine the best anthocyanin extraction protocol, we tested different kinds of developing solvents by changing the ratio of methanol, acetic acid, or HCL, and pure water. In addition, we used three kinds of frozen blueberries: soaked in acetic acid for 24 hours, only soaking the skin in acetic acid for 24 hours, and without soaking in acetic acid. The best developing solvent was a ratio of 9:2:9 with blueberry that was not soaked in acetic acid, resulting in a PCE over 0.8%.
用柱层析法从冷冻蓝莓中提取含有花青素染料的天然染料敏化太阳能电池
以冷冻蓝莓花青素为原料,采用柱层析法制备了染料敏化太阳能电池。为了确定花青素的最佳提取方案,我们通过改变甲醇、醋酸或盐酸与纯水的比例,对不同的显影溶剂进行了测试。此外,我们还使用了三种冷冻蓝莓:醋酸浸泡24小时,醋酸只浸泡皮肤24小时,不浸泡醋酸。最佳显影溶剂为未浸泡过醋酸的蓝莓与蓝莓的比例为9:2:9,显影率大于0.8%。
