【摘要】：二十一世纪的今天,科技日新月异,技术迅猛发展。不可再生能源一方面严重污染环境,另一方面随着人类的大量使用已经日渐枯竭,必须发展一种高效绿色的清洁能源来应对上述情况。近些年来,太阳能的光电技术成为了大部分科研工作者的工作重点,这个范围已经成为最具发展前景、最有科研价值的方向。依据使用材质的差异,我们可以将太阳能电池分成:硅太阳能电池、多元化合物薄膜太阳能电池、有机物太阳能电池和纳米晶太阳能电池。与传统的一些发电方法对比,太阳能电池具备大量优势:可再生,清洁易得无污染,安全无噪音,无燃料消耗,无地域限制,易于维护,建设时间短,可大规模应用。而有机太阳能电池拥有便宜、质量轻、体积小等优点,已成为光电科技领域关注的重中之重。本文主要研究的是应用于薄膜太阳能电池上的硫代双烯型金属配合物近红外染料。简要介绍了近红外染料的分类、硫代双烯型金属配合物在国内外的发展状况、合成方法和科研预期。以改善活性材料的稳定性,改变活性材料的应用时间为目的。同时为了提高有机太阳能电池的全光谱吸收,在研究和总结现存的有关文献和专利的前提下,本文设计了一种含长碳链的硫代双烯镍配合物作为电池的活性材料。由于碳链的延长,提高活性材料溶解性的同时,也使得活性材料的最大吸收波长随溶剂极性增大而向长波长方向移动。以萘酚为基础原料,制备了一种烷氧基萘酚,然后与草酰氯进行傅克反应,制备出烷氧基萘基乙二酮,最终合成了目标化合物。本文制备并表征了两种硫代双烯型金属配合物,它们的结构是经过红外光谱、核磁共振氢谱以及核磁共振碳谱,而被彻底表征的;紫外光谱测试结果表明:两种配合物在920nm左右都具有较强的紫外吸收;经过热重分析:两种配合物对热都具有较好的稳定性。由此可以得出:在近红外吸收方面这两种硫代双烯型金属配合物都拥有极好的应用价值。
[Abstract]:21 century today, science and technology with each passing day, rapid development of technology. On the one hand, non-renewable energy seriously pollutes the environment, on the other hand, with the extensive use of human beings, it is necessary to develop a kind of efficient and green clean energy to deal with the above situation. In recent years, photovoltaic technology of solar energy has become the focus of most scientific research workers, which has become the most promising and most valuable research direction. Solar cells can be divided into silicon solar cells, multicompound thin film solar cells, organic solar cells and nanocrystalline solar cells, depending on the material used. Compared with some traditional power generation methods, solar cells have a lot of advantages: renewable, clean and pollution-free, safe and noise free, no fuel consumption, no geographical restrictions, easy maintenance, short construction time, and can be applied on a large scale. Organic solar cells have the advantages of low cost, light weight and small size. In this paper, the near infrared dyes of thiobene-type metal complexes used in thin film solar cells are studied. The classification of near infrared dyes, the development of thiobenzene metal complexes at home and abroad, the synthetic methods and the prospect of scientific research are briefly introduced. In order to improve the stability of active materials and change the application time of active materials. At the same time, in order to improve the full spectral absorption of organic solar cells, on the premise of researching and summarizing the existing literatures and patents, a thiobenzene nickel complex containing long carbon chain was designed as the active material of the cell. Because of the prolongation of the carbon chain, the solubility of the active material is improved, and the maximum absorption wavelength of the active material shifts to the long wavelength with the increase of the solvent polarity. A alkoxy naphthol was prepared from naphthol and then reacted with oxaloyl chloride to prepare alkoxy naphthyl ethanedione. Finally, the target compound was synthesized. In this paper, two kinds of thiobenzene metal complexes were prepared and characterized. Their structures were characterized by IR, NMR and NMR carbon spectra. The UV spectra showed that the two complexes had strong UV absorption in 920nm and the thermogravimetric analysis showed that the two complexes had good thermal stability. It can be concluded that these two thiobenzene metal complexes have excellent application value in near infrared absorption.
