【摘要】：致密層對染料敏化太陽能電池（DSSC）光電性能的提高具有重要的意義。致密層的引入可以抑制導電基底上電子與電解液中I-3的電子復合。本論文是針對染料敏化太陽能電池光陽極材料致密層TiO2、ZnO的制備及性能的研究。 研究了TiO2致密層的兩種制備方法：以鈦酸丁酯為前驅(qū)體的水熱反應合成TiO2粒子并配置成溶膠制備TiO2致密層和以月桂胺鹽酸鹽為形貌控制劑的溶膠凝膠法直接合成TiO2溶膠制備TiO2致密層。通過比較兩種方法的實驗流程、所得TiO2致密層的形貌及所制成DSSC的光電轉(zhuǎn)化性能，證明了該溶膠凝膠法可制得含有粒徑8～10nm的銳鈦礦型TiO2粒子的溶膠，且該溶膠均勻透明，利于旋涂法制膜。所得TiO2薄膜致密平整，，具有良好的阻擋導電基底與電解液直接接觸的作用。溶膠凝膠法制備致密層工藝簡單，無需高溫高壓，且效果突出，得到的TiO2致密層具有良好的抑制電子復合和改善TiO2連接性的作用。制備三層TiO2致密層的染料敏化太陽能電池短路電流密度和光電轉(zhuǎn)化效率分別提高了15.1%和25.6%。 采用溶膠凝膠法分別制備ZnO、TiO2溶膠并旋涂制得含有三層底部ZnO致密層和兩層TiO2致密層的復合致密層，引入該種ZnO/TiO2致密層的染料敏化太陽能電池短路電流密度、開路電壓及光電轉(zhuǎn)化效率分別提高了15.3%、3.7%和29.6%。通過電化學性能測試如交流阻抗測試、開路電壓衰減測試及電池暗電流測試，進一步明確了致密層對染料敏化太陽能電池光電性能的影響。
[Abstract]:The dense layer plays an important role in improving the photoelectricity performance of Dye-sensitized Solar cells (DSSCs). The introduction of dense layer can inhibit the electron recombination between the conducting substrate and I-3 in electrolyte. In this paper, the preparation and properties of TIO _ 2O _ 2 ZnO as a dense layer of dye sensitized solar cell photoanode materials were investigated. Two preparation methods of TiO2 dense layer were studied: synthesis of TiO2 particles by hydrothermal reaction with butyl titanate as precursor and preparation of TiO2 dense layer by collocation of sol and direct synthesis of TiO2 by sol-gel method with lauryl amine hydrochloride as morphology control agent TiO2 dense layer was prepared by TiO2 sol. By comparing the experimental process of the two methods, the morphology of the dense layer of TiO2 and the photoelectric conversion properties of the prepared DSSC are obtained. It is proved that the sol containing 8~10nm particle size anatase type TiO2 particles can be prepared by the sol-gel method, and the sol is uniform and transparent. It is propitious to spin coating film. The obtained TiO2 thin films are compact and smooth, and have a good effect of blocking the direct contact between the conductive substrate and the electrolyte. The preparation process of dense layer by sol-gel method is simple, no need of high temperature and high pressure, and the effect is outstanding. The obtained TiO2 dense layer has a good effect on inhibiting electron recombination and improving TiO2 connectivity. The short-circuit current density and photoelectric conversion efficiency of the dye sensitized solar cells prepared by the three-layer TiO2 dense layer were increased by 15.1% and 25.6%, respectively. The composite dense layer containing three layers of ZnO dense layer at the bottom and two layers of TiO2 dense layer were prepared by sol-gel method. The dye sensitized solar cell short-circuit current density of the ZnO/TiO2 dense layer was introduced. The open circuit voltage and photoelectric conversion efficiency were increased by 15. 3% and 29. 6% respectively. The effect of dense layer on the photovoltaic performance of dye sensitized solar cells was further clarified by electrochemical performance tests such as AC impedance test, open circuit voltage attenuation test and cell dark current test.
