摘要

奈米碳管具有許多優良的物理特性，諸如高長徑比、高熱傳性、高電導性、高鋼性等，往往為改良材質性質的首選配方。太陽能電池為現今最熱門的綠色能源之一，其中有機高分子太陽能電池更擁有質輕、可撓、成本低廉，以及適於製作大面積元件等特點。截至今日，許多研究指出於光致電壓主動層中混入多壁奈米碳管，能夠具體提升高分子的載子移動率，進而增進有機高分子太陽能電池的光電轉換效率。
田口品質工程法因其具有精簡實驗次數以及高準確度的特性，為目前世上應用最廣泛的主流製程參數設計法。本篇研究將以田口法探討奈米碳管/高分子複合有機太陽能電池的穩健製程設計，以尋求其最佳參數以及製作流程。根據本篇結果，透過最佳參數製程所得的奈米碳管/高分子複合有機太陽能電池，的確能獲得較佳的光電轉換效率。

MWCNT (multiwalled carbon nanotube) is a popular candidate formula of material improving because of its unique properties: high aspect ratio, good thermo-conductivity, large electrical conductivity, and great stiffness. At present, solar cell is the most popular green energy choice in the world. The polymer based organic solar cells not only inherits all characteristics of traditional solar device but has some advantages such as: lightweight, flexibility, cost-effectivity, and suitable for large-area devices. Some researches show the polymer-based active layer mixed with MWCNT can increase the carrier mobility and then enhance the performance of the solar cells. Taguchi method is a worldwide used parameters design method due to the features of time saving and accuracy. This paper presents a new Taguchi robust design of organic solar cell consisting of MWCNT/polymer, and obtains the optimum parameters of fabricating process. The results show the polymer solar cells made by optimum parameters can achieve the better photovoltaic chracteristics.
