Description
技术领域
本发明属于电化学技术领域,主要涉及一种用于染料敏化太阳能电池的石墨烯复合硒、钴元素对电极的制备方法。
背景技术:
染料敏化太阳能电池(DSSC)作为一种环境友好型、高效的新型太阳能电池,具有生产工艺简单、环境污染小、制备过程耗能小,对环境温度依赖小,成本低廉等优点,有着广阔的发展空间,它的商业化应用价值也日趋明显。
在染料敏化太阳能电池中,对电极是电池的正极,其主要作用是,接受电池外电路中的电子并将这些电子传递给电解液的氧化还原电子对。传统的染料敏化太阳能电池大多都是以Pt作为对电极,Pt是最佳的催化材料,然而Pt属于稀有金属、价格昂贵,大规模应用时必须要考虑价格因素对电池成本的影响。因此,开发一种来源丰富、低成本,转换效率较高的材料替代Pt来制备对电极是染料敏化太阳能电池器件的重要研究内容之一。
石墨烯(Graphene)是一种六角蜂窝状、二维平面结构的新型碳材料。自2004年被英国曼彻斯特大学的两位科学家安德烈·杰姆和克斯特亚·诺沃消洛夫发现以来,其优异的光学、电学、力学等物理特性,以及广泛的应用前景,在材料科学领域引起了巨大的关注。例如,石墨烯具有非同寻常的导电性能,在石墨烯中,电子能够极为高效地迁移,传统的硅、铜等导体和半导体材料都远没有石墨烯表现得好。而且石墨烯具有超出钢铁数十倍的强度并兼具极好的透光性。石墨烯的出现有望在现代材料、化学、电子科技等领域引发新的变革,被称为“神奇材料”,有科学家甚至预言其将“彻底改变21世纪”。
石墨烯是一种单层二维材料,它可以卷曲制备出零维的富勒烯和一维的碳纳米管,也可以堆积成三维的石墨。在纳米电子器件、气体传感器、能量存储及复合材料等领域都有广泛的应用,因此一直引起科学界的广泛关注。又因近年来的研究发现石墨烯在热、电、磁、空间结构等特性的优良性质,使得石墨烯在太阳能电池、燃料电池等方面具有良好的应用前景。
许多研究发现:石墨烯的边缘位和石墨烯基面的电化学性质存在着明显的差异,石墨烯边缘位具有较高的电化学活性,而石墨烯基面是电化学惰性的。为了使石墨烯材料的催化活性提高,需要对其进行基面进行活性化,通过掺杂其它元素可以有效的控制其基面的电子结构,提高电导率。因此,活化石墨烯基面,提高石墨烯电催化活性的有效途径之一。
发明内容
为了克服上述现有技术中的不足,本发明提供了一种操作方法简单,成本低、时间短、对环境友好、无繁琐的后续处理,只需将各种原料按比例加入具有聚四氟乙烯内胆的不锈钢反应釜中,反应12小时取出产品,用无水乙醇清洗数次,室温条件下晾干即可,所得的产品表面分布均匀,重复性较好,致密度较高的优点的将该复合的石墨烯/钴、硒材料应用为染料敏化太阳能电池对电极的制备材料的方法。
