微奈米小球之組裝與應用研究
Investigation on Assembly of Micro/Nano-Spheres and Its Applications
摘要
本論文中以旋轉塗布結合過水轉印法（Spin with Water-Transfer）製作出微奈米小球自組單層膜（Micro/Nano-Sphere Self-Assembled Monolayer），並將微奈米小球單層膜應用於染料敏化太陽能電池（Dys-Sensitized Solar Cell）以提升其電性表現及電池效率。 使用微奈米小球單層膜利用微奈米小球微影術（Nanosphere Lithography），以蒸鍍方式製作出二氧化矽奈米結構，並將此奈米結構蒸鍍上白金，做為染料敏化太陽能電池之白金對電極（Platium Counter Electrode），經實驗結果可以發現太陽能電池電壓電流特性（Current-Voltage Characteristic）、光電轉換效率（Incident Photon to Current Conversion Efficiency）、電化學阻抗（Electrochemical Impedance）等等電性特徵較一般太陽能電池佳。為使染料敏化太陽能電池之電性表現達最佳化，本研究以不同尺寸之奈米小球，及不同尺度之奈米結構進行實驗，結果顯示應用微奈米小球製成奈米結構之電池，其電池效率最多可提升27.3%。此外，採用旋轉塗布結合過水轉印法製作微奈米小球單層自組膜，可以簡單之製成方式製作大面積且缺陷較少之小球單層膜。 利用微奈米小球自組單層膜製成之奈米結構，本研究所研製之染料敏化太陽能電池已成功增進多項電性表現，進而提升電池效率。微奈米小球自組膜除了在太陽能電池的應用之外，在未來亦可應用於更多領域之發展。

In this thesis, based on the “spin with water-transfer” method, the fabrication of micro/nano-sphere self-assembled monolayers has been developed and applied to dye-sensitized solar cell (DSSC). The self-assembled micro/nano-sphere monolayer was used to fabricate the nanostructured platinum counter electrode of DSSC in which silicon dioxide nanostructures were first formed utilizing the nanosphere lithography and then coated by platinum. The performances of DSSCs with the nanostructured platinum counter electrodes are superior to those of conventional solar cells in the photocurrent, incident photon to current conversion efficiency, and electrochemical impedance. To optimize performances, micro/nanospheres of various sizes and nanostructured silicon dioxide of varied thicknesses had been studied in this thesis. Compared to conventional DSSCs, the efficiency of DSSC with nanostructured platinum counter electrode was improved by 27.3%. Furthermore, utilizing the “spin and water transfer” method, it is able to fabricate large-area micro/nano-sphere self-assembled monolayers with less defects and simpler processes.
