Description
技术领域
本发明涉及太阳能电池材料技术领域,具体涉及一类碗烯基钙钛矿太阳能电池空穴传输层材料及其制备方法和应用。
背景技术
随着社会的快速发展,环境污染和能源危机逐渐成为人类面临的两大社会问题。开发风能、潮汐能和太阳能等新能源迫在眉睫。太阳能取之不尽,用之不竭,将太阳能直接转化为电能的太阳能电池受到广大研究者们的青睐。在众多太阳能电池中,钙钛矿太阳能电池(PSCs)由于具有可溶液加工、低成本和易大面积制备等优点被广泛研究。在过去不到十年的时间里,钙钛矿太阳能电池的光电转换效率持续上升。目前,文献报道钙钛矿太阳能电池的效率达到24%(Joule,2019,3,2179-2192),接近商业化的门槛。伴随着越来越多新型材料的问世,钙钛矿太阳能电池作为一种新型电池正展现着出前所未有的活力。为了提升钙钛矿太阳能电池的稳定性与光电转换效率,科学家对钙钛矿太阳能电池中的五个部分——玻璃基底、电子传输层、钙钛矿吸光层、空穴传输层和金属电极进行优化和改良。空穴传输层是钙钛矿太阳能电池的关键组成部分之一,主要作用是收集、传输光生空穴和抑制载流子的复合,阻止水氧进入钙钛矿。优化空穴传输层对于提高钙钛矿太阳能电池的效率和稳定性具有十分重要的意义。对于空穴传输层材料来说,它们都具有较大π共轭平面或者立体结构的内核以及给电子的功能基团(如Spiro-OMeTAD)。目前,研究者们已开发了大量的不同类型的空穴传输层材料。现有的工作普遍致力于更改内核或调整给电子功能基团的结构和空间位置,从而改变分子的能级、溶解性、堆积方式、空穴传输性能和电池稳定性等。
迄今为止,有许多新报道的空穴传输材料用于钙钛矿太阳能电池,都呈现出良好的性能:(Chem.Sci.,2016,7,5007-5012;Asian J.Org.Chem.,2018,7,2182–2200;Nat.Energy,2016,1,15017;Nature Energy,2018,3,682–689;Angew.Chem.Int.Ed.,2018,57,10959–10965)。
与蒄等平面π共轭分子不同,碗烯(Corannulene)是用来合成非平面π共轭分子的关键和代表性结构之一。它是一种由一个五元环周围稠合五个苯环而形成的碗状多环芳香碳氢化合物,于1966年由科学家Barth和Lawton首次合成。一直以来,碗烯被视作C60的碎片,其具有与C60相似的曲面和π共轭体系,并呈现出特殊的化学和物理性质。因此,碗烯的合成及其性质研究是一个倍受关注并且十分活跃的领域。为了进一步研究碗烯的一系列性质,必须对其进行进一步的功能化修饰和探索。研究发现,大部分碗烯功能化衍生物拥有优异的电学光学性质,在超分子自组装方面也有着特殊的性质(Nat.Common.,2019,10,485),且在有机场效应晶体管(OFETs)和有机太阳能电池(OPVs)等领域也有很大的发展前景(Chem.Sci.,2014,5,1041–1045)。
目前,虽然有很多碗烯衍生物被合成得到,也证明了这些衍生物拥有一定的电学性质,但现有的碗烯衍生物不但制备过程复杂,生产成本较高,而且稳定性较差及光电转换效率较低,很难满足人们的使用需求。
发明内容
本发明的目的之一在于提供一类碗烯基钙钛矿太阳能电池空穴传输层材料。以碗烯分子为核,引入不同的给电子功能基团。一是以非平面的碗烯作为分子内核,能有效提高空穴传输材料分子在有机溶剂中的溶解度;二是碗烯独特的五取代结构,其相较于Spiro-OMeTAD能提供更多连接给电子功能基团的位点;三是碗烯作为拥有较大π共轭体系的非平面分子,为整个空穴传输材料分子形成更大的π共轭体系,获得了一类具有高玻璃转化温度的碗烯基空穴传输材料,制备过程简单方便,可用于提高钙钛矿太阳能电池的稳定性与光电转换效率。

优选地,Q是π电子连接单元或无需Q单元,为以下化学结构式的一种:
其中,X为氧原子、硫原子、硒原子、氮原子和硅原子;R1-R12独自选自H原子、芳基、羟基、胺基、卤素原子或碳原子数为1-10直链或支链烷基、碳原子数为1-10直链或支链烷氧基、碳原子数为1-10直链或支链烷硫基和碳原子数为1-10直链或支链的胺。

上述制备方法中,化合物3的合成方法具体为:取双口圆底烧瓶,无水无氧处理,依次加入产物1、π电子连接单元2、四三苯基膦钯催化剂、碳酸铯,置换气体3次,氮气保护下加入N,N二甲基甲酰胺进行Suzuki偶联反应,加热反应温度为20~120℃之间。反应过夜,TLC监测反应结束后,冷却至室温后加入水淬灭,将反应原液转移到分液漏斗中用二氯甲烷萃取,有机相用无水硫酸钠干燥,减压旋转蒸发溶剂后用石油醚/二氯甲烷作为洗脱剂过硅胶柱分离得到黄红色固体;所述的化合物1、π电子连接单元2、四三苯基膦钯催化剂、碳酸铯、N,N二甲基甲酰胺配比为0.2~2mmol:0.16~16mmol:0.1~0.8mmol:3~15mmol:10~50mL,反应温度为20~120℃,具体可为20℃或120℃,反应时间为5~24h,具体可为5h或24h。
本发明先合成具有三苯胺结构的***给电子单元,然后通过与碗烯(Corannulene)五硼酯中间体进行Suzuki偶联缩合反应合成具五取代结构的碗烯基钙钛矿太阳能电池空穴传输层材料,制备工艺简单、可控。
本发明提供了一类碗烯基钙钛矿太阳能电池空穴传输层材料在钙钛矿太阳能电池方面的应用,该碗烯基钙钛矿太阳能电池空穴传输层材料均有高效的光电转化效率。
采用上述技术方案后,本发明与背景技术相比,具有如下有益效果:
1、本发明提供的一类碗烯基钙钛矿太阳能电池空穴传输层材料的制备方法,首次合成了一类具有五取代结构的碗烯基钙钛矿太阳能电池空穴传输层材料。
2、本发明提供的化合物的合成从碗烯的硼酯化衍生物出发,实验步骤仅2~3步,简单有效。
