摘要

抽象。该研究进行了对叶绿素和花青素的电化学提取物和花青素提取物的分析,研究对象是红龙(咽喉)和红龙果皮(Hylocereus Polyrhizus),即对太阳能电池(DSSC)的敏感反应。红龙果皮中的叶绿素和花青素果皮中的叶绿素是用乙醇溶剂提取的。叶绿素和花青素的特点是利用可见光谱分析来确定波长和带状能量的传播,而非叶绿素和花青素电化学和花青素的电化学和花青素特性。这项研究产生了叶绿素,其波长为663 nm,波长为439 nm,波长为532 nm。分析叶绿素色带间隙产生2.51 eV和花青素2.1 eV。电化学特征表明,叶绿素的能量(Highest Occupied分子轨道)为- 5.68 eV,花青素为- 5.16 eV。叶绿素的能量为- 3.17 eV,花青素为- 3.06 eV。这一结果表明,杉本叶绿素和花青素提取物和红龙果皮的提取物具有相当大的潜力,可以在DSSC上用作光泽剂。关键词:花青素,DSSC,电化学,叶绿素摘要。在这项研究中,一种由素二和红龙果实果皮进行的电化学分析将其归因于对太阳能电池的敏感敏感。来自suji的氯磷酸从红龙果实的皮肤中提取,红龙果实的鳞茎正在使用乙醇作为溶剂。用气旋电压和电化学特性测定被UV-Visible specdgaps发现异常和能量链的衰减,即氯化氢和花青素的电化学作用作用被cyclic voltammetry分解。在这项研究中,氯仿是由663 nm和439 nm的腐败行为生产的,而花青素是532 nm wavelengths。分析氯仿yields 2.51 eV和钩针2。1 eV的能量平衡。电化学作用表明氯氧氧中最活跃的分子能量是5。68叶绿体中的能量为3.17这些迹象表明,从苏集提取的氯和花青素和红龙果实可能很难用于DSSC的照片使用。青蒿素,叶绿素,DSSC,电化学
