【摘要】：聚合物太陽能電池由于其具有質(zhì)量輕,成本低,機(jī)械柔性好以及易于實(shí)現(xiàn)大面積的生產(chǎn)等優(yōu)點(diǎn),成為當(dāng)下研究的熱點(diǎn)。但當(dāng)前聚合物太陽能電池的效率還是較低,目前提高聚合物太陽能電池效率的途徑主要通過設(shè)計(jì)合成新的活性層材料,活性層的形貌調(diào)控以及電極和活性層之間的界面優(yōu)化等。其中電極和活性層之間的界面優(yōu)化起著非常重要的作用。良好的界面層材料不僅可以改善無機(jī)的金屬電極和有機(jī)的活性層之間的接觸,降低界面勢壘;還能夠調(diào)節(jié)各接觸界面的能級,提高電荷的選擇性,進(jìn)而促進(jìn)電荷的傳輸和收集,最終提高器件的效率。同時(shí),界面層還能有效地避免空氣中水氧的侵蝕,在一定程度上還能提高器件的穩(wěn)定性。本論文主要研究功能化的納米氧化鋅(nano-ZnO)作為陰極緩沖層來優(yōu)化聚合物太陽能電池的性能。首先我們用水熱法制備了氧化鋅納米陣列(ZnO NAs),并對所得到的ZnO NAs進(jìn)行了相應(yīng)的性能測試和表征。為了減小Zn O NAs表面的缺陷,改善ZnO NAs表面性能,提高聚合物太陽能電池的光電性能,我們用連續(xù)離子吸附法生長的CdS納米層作為表面改性劑對其進(jìn)行表面功能化。引入CdS納米層對ZnO NAs表面進(jìn)行功能化后,聚合物太陽能電池的光電流(Jsc),開路電壓(Voc),填充因子(FF)和器件光電轉(zhuǎn)化效率(PCE)均得到了較為明顯地提高。而且在雜化太陽能電池器件結(jié)構(gòu)中,引入CdS納米層后,雜化太陽能電池的相關(guān)器件性能參數(shù)也得到了明顯的提高。而且為了簡化實(shí)驗(yàn)的工藝,隨后我們還用全(十三)氟辛基三乙氧基硅烷來氟化ZnO NPs,并將其摻入到活性層中。由于含氟烷基鏈的表面能較低,經(jīng)過溶劑退火,含氟的氧化鋅納米粒子(用Zn OF NPs來表示)會(huì)自發(fā)的上漂形成一薄層電子傳輸層,最終達(dá)到能夠改善有機(jī)活性層和電極間的接觸又能夠簡化實(shí)驗(yàn)工藝的目的。綜上,設(shè)計(jì)一個(gè)好的界面層材料不僅能夠提高器件的效率,還能夠簡化器件制備的工藝,降低成本,這對以后的大面積商業(yè)化生產(chǎn)大有裨益。而且結(jié)合無機(jī)納米晶和有機(jī)聚合物各自的優(yōu)點(diǎn),設(shè)計(jì)新型的界面材料必將對于太陽能電池的發(fā)展作出巨大貢獻(xiàn)。
[Abstract]:Polymer solar cells have become the focus of research because of their advantages of light quality, low cost, good mechanical flexibility and easy to realize large area production. However, the efficiency of polymer solar cells is still low at present. At present, the main way to improve the efficiency of polymer solar cells is to design and synthesize new active layer materials. The interfacial optimization between the electrode and the active layer plays a very important role in the interface optimization between the electrode and the active layer. The good interface material can not only improve the contact between the inorganic metal electrode and the organic active layer, lower the interface barrier, but also can adjust the contact interface. At the same time, the interface layer can effectively avoid the erosion of water and oxygen in the air and improve the stability of the device to a certain extent. This paper mainly studies the functionalized nano Zinc Oxide (nano-ZnO) as the cathode buffer layer to optimize the polymerization. The performance of the hybrid solar cells. First, we prepared the Zinc Oxide nanoarray (ZnO NAs) by hydrothermal method, and carried out the corresponding performance testing and characterization of the obtained ZnO NAs. In order to reduce the defects of the Zn O NAs surface, improve the NAs surface performance of ZnO and improve the photoelectric performance of the polymer solar energy battery, we use continuous ion adsorption method. The surface functionalization of the growing CdS nano layer as a surface modifier. After introducing the CdS nano layer to the function of the ZnO NAs surface, the photocurrent (Jsc), the open circuit voltage (Voc), the filling factor (FF) and the photoelectric conversion efficiency (PCE) of the polymer solar cells have been greatly improved. Moreover, the hybrid solar cell is used in the hybrid solar cell. In the structure, after the introduction of the CdS nano layer, the performance parameters of the related devices of hybrid solar cells have also been significantly improved. In order to simplify the experiment process, we also fluorinate ZnO NPs with all (thirteen) fluorocococyl triethoxy silane and add it to the active layer. The fluorinated Zinc Oxide nanoparticles (expressed by Zn OF NPs) will spontaneously float up to form a thin layer of electron transport layer, and finally achieve the purpose of improving the contact between the organic active layer and the electrode. In the end, the design of a good interface material can not only improve the efficiency of the device, but also simplify the efficiency of the device. The process of device preparation reduces the cost, which is of great benefit to large-scale commercial production in the future. Moreover, combining the advantages of inorganic nanocrystals and organic polymers, the design of new interface materials will make great contributions to the development of solar cells.
