Description
技术领域
本发明涉及有机染料技术领域和精细化工中的光电转化材料应用领域,具体涉及一种三苯基二氢吖啶染料及其制备方法与在染料敏化太阳电池中的应用。
背景技术
1991年染料敏化太阳能电池(DSSCs)的光电转换效率创造性的达到具有可实际开发并大规模应用的价值,而后,人们对染料敏化太阳能电池进行了长远的研究与探索极,推动了染料敏化太阳能电池工业技术的飞速发展。研究者所追求的目标一直都是高效且能长期稳定的纯有机敏化染料。敏化染料作为DSSCs中必不可少的关键部组分,主要作用是产生和传递光生电子。金属配合物染料和纯有机染料是敏化染料的主要分支。其中纯有机染料结构便于设计调控、消光系数高、原料廉价易于获得等优点,受到研究者的青睐。纯有机染料一般具有D-π-A型的结构,为了进一步促进分子内部电子转移,拓宽光谱响应范围,研究者们又开发出D-A-π-A型的敏化染料,额外辅助受体的引入使得分子内部电子推拉能力增强,光电流得到极大提升。但是同时发现辅助受体的引入会使分子共轭性增强进而染料分子间容易发生π-π堆积,影响DSSCs器件的性能(1.Han,L.;Liu,J.;Liu,Y.;Cui,Y.,NovelD-A-π-A type benzocarbazole sensitizers for dye sensitized solarcells.Journal of Molecular Structure 2019,1180,651-658;2.Xie,Y.;Zhou,H.;Zhang,S.;Ge,C.;Cheng,S.,Influence of the auxiliary acceptor andπ-bridge intriarylamine dyes on dye-sensitized solar cells.Photochemical&PhotobiologicalSciences 2019,18(8),2042-2051)。而减少分子间的聚集,可以通过在染料骨架中引入一些烷基链或者大位阻的基团。关于烷基链的引入已经有很多报道,而对大位阻的基团的研究比较少。
二氢吖啶此前被广泛的应用在有机发光二极管(OLED)中,展现了优秀的供电子能力以及空穴传输能力。而三苯基二氢吖啶在二氢吖啶的基础上引入了额外的苯基。当其作为供体时,苯基的引入有利于增强染料分子的供电性,并且当把两个苯基取代到吖啶上的时候,由于空间位阻效应,整个结构具有相互垂直的特征。这种垂直的空间结构能有效地抑制分子间的聚集,并减少暗电流,提高开路电压。其次,喹喔啉作为一个优异的吸电子基团,将其引入染料中,能拓宽分子的光吸收范围,且自身优异的光化学稳定性,使其成为辅助受体的优异选择。在π桥上,低聚噻吩的引入,可以扩大染料分子平面共轭,增强捕光捕光性能,对染料的效率产生积极影响。

(6)绝缘塑料膜打完孔后,使其内孔恰好覆盖在制备好的光阳极上,在光阳极膜滴上0.1ml的制备完成的电解液,并在光阳极上紧密盖上制备的铂对电用夹子将极两边固定,得到开放性敏化染料太阳电池。
电池器件的光电性能测试(测试方法的标准见中华人民共和国国家标准GB11009-89):
将步骤(6)制备的开放性敏化染料太阳电池与电池性能测试装置–太阳光模拟器(Pecell-L15,Japan)联通,电池的工作面积为0.16cm2,模拟太阳光,将光强度调节至100mW/cm2,然后测试电池的J-V曲线。
所测得的染料敏化太阳电池的J-V曲线图如图2所示,数据汇总于表2。
表2染料DDQL用于染料敏化太阳电池性能数据
aAFL9分子引用参考文献(Photochemical&Photobiological Sciences 2019,18(8),2042-2051)。
从图2和表2的数据可以看出,参考染料AFL9的供体是三苯胺的衍生物,辅助受体是苯并噻二唑,也具有D-A-π-A的结构,从上述表格可以看出,AFL9具有较低的短路电流,这是由于分子具有大共轭的平面,会导致染料发生严重的聚集,使得光生电子淬灭,降低电子注入速率。而染料DDQL由于引入了大位阻的供体三苯基二氢吖啶,可以有效地抑制分子间的聚集,减少暗电流,因此获得了更高的短路电流,DDQL敏化的染料敏化太阳电池表现出色的光电转换效率。
以上实施例仅为本发明较优的实施方式,仅用于解释本发明,而非限制本发明,本领域技术人员在未脱离本发明精神实质下所作的改变、替换、修饰等均应属于本发明的保护范围。
