【摘要】：目前,在光伏器件領(lǐng)域,全固態(tài)鈣鈦礦太陽(yáng)能電池的研究十分活躍。混合有機(jī)-無(wú)機(jī)鈣鈦礦太陽(yáng)能電池通常使用有毒試劑N,N-二甲基甲酰胺(DMF)和二甲基亞砜(DMSO)制備鈣鈦礦薄膜,因此開發(fā)制備環(huán)境友好型、制備簡(jiǎn)單、成本低的無(wú)毒試劑對(duì)于全固態(tài)太陽(yáng)能電池具有重要的意義。在以上背景條件下,本文對(duì)以下兩方面的工作內(nèi)容進(jìn)行了研究。本文將兩步旋涂制備鈣鈦礦太陽(yáng)能電池法與水-乙醇體系溶劑相結(jié)合,實(shí)現(xiàn)了鈣鈦礦太陽(yáng)能電池中高質(zhì)量鈣鈦礦薄膜的制備。將非鹵素鉛源Pb(NO3)2配制成濃度為1M的水溶劑溶液,并且向其中添加表面活性劑surfynol465,然后通過(guò)兩步旋涂法將溶液沉積在多孔二氧化鈦(Ti02)薄膜上,再與碘甲胺(CH3NH3I)反應(yīng)制備了鈣鈦礦。實(shí)驗(yàn)結(jié)果表明,添加表面活性劑可以顯著提高Pb(NO3)2/H2O溶液在多孔TiO2薄膜上的鋪展性,得到較為平整的薄膜。并且使用該方法制備鈣鈦礦薄膜需要重復(fù)旋涂三次才能保證Pb(N03)2完全轉(zhuǎn)化為鈣鈦礦。使用水溶劑制備的鈣鈦礦太陽(yáng)能電池的光電轉(zhuǎn)化效率達(dá)到了 12%,且具有更高的重現(xiàn)性。本文還研究了一種操作簡(jiǎn)單、靶向性強(qiáng)、材料利用率高和可大面積沉積鈣鈦礦薄膜的噴墨打印制備工藝。將Pb(OAC)2溶解于水中配制成濃度為1M的溶液,并向其中添加表面活性劑surfynol465,然后通過(guò)噴墨打印的方式制備Pb(OAC)2薄膜,最后,將墨水換成80mg/ml碘甲胺溶液沉積鈣鈦礦薄膜。實(shí)驗(yàn)結(jié)果顯示,表面活性劑surfynol465的添加量為0.5wt%時(shí)達(dá)到噴墨打印機(jī)墨水的表面張力,可以順利出墨。在此條件下,鈣鈦礦電池的光電轉(zhuǎn)化效率為13.2%。使用環(huán)境友好型水-乙醇體系溶劑作為制備鈣鈦礦的材料,很大程度上減少了環(huán)境污染問(wèn)題,對(duì)鈣鈦礦太陽(yáng)能電池以后商業(yè)化做出了堅(jiān)實(shí)的鋪墊。使用水溶劑墨水噴墨打印制備鈣鈦礦薄膜,不會(huì)腐蝕噴墨打印機(jī),是一種環(huán)境友好的制備技術(shù),可適用于大面積的低成本鈣鈦礦電池制備。
[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.
