【摘要】：目前,在光伏器件领域,全固态钙钛矿太阳能电池的研究十分活跃。混合有机-无机钙钛矿太阳能电池通常使用有毒试剂N,N-二甲基甲酰胺(DMF)和二甲基亚砜(DMSO)制备钙钛矿薄膜,因此开发制备环境友好型、制备简单、成本低的无毒试剂对于全固态太阳能电池具有重要的意义。在以上背景条件下,本文对以下两方面的工作内容进行了研究。本文将两步旋涂制备钙钛矿太阳能电池法与水-乙醇体系溶剂相结合,实现了钙钛矿太阳能电池中高质量钙钛矿薄膜的制备。将非卤素铅源Pb(NO3)2配制成浓度为1M的水溶剂溶液,并且向其中添加表面活性剂surfynol465,然后通过两步旋涂法将溶液沉积在多孔二氧化钛(Ti02)薄膜上,再与碘甲胺(CH3NH3I)反应制备了钙钛矿。实验结果表明,添加表面活性剂可以显著提高Pb(NO3)2/H2O溶液在多孔TiO2薄膜上的铺展性,得到较为平整的薄膜。并且使用该方法制备钙钛矿薄膜需要重复旋涂三次才能保证Pb(N03)2完全转化为钙钛矿。使用水溶剂制备的钙钛矿太阳能电池的光电转化效率达到了 12%,且具有更高的重现性。本文还研究了一种操作简单、靶向性强、材料利用率高和可大面积沉积钙钛矿薄膜的喷墨打印制备工艺。将Pb(OAC)2溶解于水中配制成浓度为1M的溶液,并向其中添加表面活性剂surfynol465,然后通过喷墨打印的方式制备Pb(OAC)2薄膜,最后,将墨水换成80mg/ml碘甲胺溶液沉积钙钛矿薄膜。实验结果显示,表面活性剂surfynol465的添加量为0.5wt%时达到喷墨打印机墨水的表面张力,可以顺利出墨。在此条件下,钙钛矿电池的光电转化效率为13.2%。使用环境友好型水-乙醇体系溶剂作为制备钙钛矿的材料,很大程度上减少了环境污染问题,对钙钛矿太阳能电池以后商业化做出了坚实的铺垫。使用水溶剂墨水喷墨打印制备钙钛矿薄膜,不会腐蚀喷墨打印机,是一种环境友好的制备技术,可适用于大面积的低成本钙钛矿电池制备。
[Abstract]:At present, the research of all-solid-state perovskite solar cells is very active in the field of photovoltaic devices. The mixed organic-inorganic perovskite solar cells usually use the toxic reagents NN- dimethylformamide (DMF) and dimethyl sulfoxide (DMSO) to prepare perovskite films. Low-cost non-toxic reagents are of great significance for all-solid solar cells. Under the above background condition, this paper has carried on the research to the following two aspects of work. In this paper, the preparation of high quality perovskite thin films in perovskite solar cells by two-step spin coating method and water-ethanol system solvent was studied. Non-halogen lead source Pb (NO3) _ 2 was prepared into water solvent solution with concentration of 1m, and then the solution was deposited on porous titanium dioxide (Ti02) thin film by two-step spin coating method, and then perovskite was prepared by reaction with iodomethylamine (CH3NH3I). The experimental results show that the spreading property of Pb (NO3) 2/H2O solution on porous TiO2 films can be significantly improved by adding surfactants, and a flat film can be obtained. The Pb (N03) 2 can be completely converted to perovskite by using this method to prepare perovskite thin films by repeated spin-coating three times in order to ensure the complete conversion of Pb (N03) 2 to perovskite. The photovoltaic conversion efficiency of perovskite solar cells prepared with water solvent is up to 12 and has higher reproducibility. This paper also studies a kind of ink jet printing technology which is easy to operate, has strong targeting, has high material utilization and can deposit perovskite thin film in large area. Pb (OAC) _ 2 was dissolved in water to form a solution with concentration of 1m, then the surfactant surfynol465, was added to the solution, then the Pb (OAC) _ 2 thin film was prepared by inkjet printing. Finally, the ink was replaced by 80mg/ml iodomethylamine solution to deposit perovskite film. The experimental results show that the surface tension of inkjet printer ink can be reached when the amount of surfactant surfynol465 is 0.5 wt%, and the ink can be produced smoothly. Under these conditions, the photoconversion efficiency of perovskite battery is 13.2g. Using the solvent of environment-friendly water-ethanol system as the material for preparing perovskite greatly reduces the problem of environmental pollution and lays a solid foundation for the commercialization of perovskite solar cells. The preparation of perovskite thin films by using water-solvent ink inkjet printing is a kind of environmentally friendly preparation technology, which can be used to prepare large area low-cost perovskite batteries.
