摘要

本論文成功合出多面體矽倍半氧寡聚物 (POSS)、硫化鎘 (CdS)、硫化鉛(PbS)、金 (Au) 等四種具有不同特性的奈米粒子，並利用長碳鏈硫醇 (alkane thiol)、油酸 (oleic acid)、硫酚 (thiopheol) 進行表面修飾，合成出含有飽和長碳鏈的POSS-SC16、CdS-SC12、Au-SC12、PbS-OA與稍具價荷傳導能力的硫酚CdS-SPh奈米粒子。即使是CdS-SPh，這些奈米粒子在一般有機溶劑中皆有足夠的溶解度，適合溼式製程的聚(3-已烷基噻吩) (P3HT)/[6,6]-苯基-碳61-丁酸甲酯 (PCBM)異質接面太陽能電池。此摻混有奈米粒子的P3HT/PCBM系統，使用穿透式電子顯微鏡 (TEM)、原子力顯微鏡 (AFM)、紫外光-可見光吸收光譜儀 (UV-Vis)、X-ray繞射光 (XRD) 與螢光光譜儀 (PL)來觀察對元件與電性上的變化與影響。

In this study, polyhedral oligomeric silsesquioxanes (POSS), cadmium sulfide (CdS), lead sulfide (PbS) and gold (Au) nanoparticles were synthesized and characterized. Having modification of long saturated hydrocarbon chains (POSS-SC16、CdS-SC12、AuSC12、PbS-OA) and aromatic thiophenol (CdS-SPh), these nanoparticles exhibited good solubility in common organic solvents. Thus, these nanoparticles were used as additives for improving the power conversion efficiency of P3HT/PCBM solar cell in the solution process systems. Moreover, transmission electron microscopy (TEM), atomic force microscopy (AFM), UV-Vis absorption spectrometry, X-ray diffraction (XRD), and fluorescence spectrometry (PL) were investigated to elucidate the properties of these nanoparticles in P3HT/PCBM bulk-heterojunction (BHJ) solar cells.
