Andre Geim 與Konstantin Novoselov於2004年以膠帶剝離法製備出石墨烯(graphene)， 2010年因為石墨烯的開創性實驗獲得諾貝爾獎。石墨烯近幾年發展迅速，擁有優良的電學、力學、熱學特性。
本研究利用酒精氣相沉積(Alcohol Catalytic Chemical Vapor Deposition, ACCVD)的方式成長石墨烯：第一部分藉由調整酒精流量來探討製程和石墨烯品質的關係，並觀察對於層數上的影響，可以成長出8層石墨烯；第二部分改變鎳基板厚度，觀察石墨烯品質與層數的關係，控制鎳厚度可以長出單層的石墨烯；第三部分使用銅箔來成長石墨烯，探討不同基板對於成長石墨烯的影響。最後利用濕蝕刻的方式，將成長好的數層石墨烯轉移至PDMS(polydimethylsiloxane)後，應用於有機太陽能電池，效率為1.2%。

Andre Geim and Konstantin Novoselov prepared the graphene by using mechanical exfoliation method in 2004 and won Nobel Prize because of the innovative graphene experiment in 2010. The graphene has developed rapidly in recent years and it is equipped with unique electrical, mechanical and heat conductive property.
This study aims to prepare graphene via Alcohol Chemical Vapor Deposition (ACCVD) and can be divided into three aspects. In the first part, I change the alcohol flow rate in order to see the influence on the graphene quality and on the layers and we can grow 8 layers of graphene. Second, I change the nickel thickness to see the influence on the graphene quality and on the layers. I can grow graphene monolayer by control the thickness of Nickel. Third, we grow up the graphene on copper foil and see its impact on the graphene quality and on the layers.
Finally, we etch the substrate in order to transfer the graphene to PDMS after graphene growing. I transfer the graphene on P3HT, and the photovoltaic conversion efficiency is 1.2%.
