【摘要】：石墨烯是一種具備優(yōu)異的光、電、熱、力等性能的新型二維碳材料,近幾年迅速成為材料等領(lǐng)域的研究焦點,以石墨烯為基礎(chǔ)的電子器件等也吸引了大量的研究。將石墨烯作為電極應(yīng)用于有機太陽能電池的過程中,因為石墨烯表面的疏水性質(zhì),PEDOT:PSS高分子導電層不能均勻覆蓋在石墨烯表面,二者成膜性差,從而導致石墨烯為電極的有機太陽能電池的制備成功率低。從更好地將石墨烯應(yīng)用于太陽能電池中這個目的出發(fā),本文的主要內(nèi)容包括以下三部分：采用化學氣相沉積法在銅箔表面生長石墨烯,通過對部分工藝參數(shù)的調(diào)控來得到高質(zhì)量石墨烯,在生長石墨烯的金屬基底預(yù)處理步驟以及石墨烯的轉(zhuǎn)移步驟中提出簡單高效的工藝方法,進一步優(yōu)化了石墨烯的生長過程和轉(zhuǎn)移過程的工藝。針對石墨烯與PEDOT:PSS復(fù)合成膜性差這個問題,提出了兩種有效解決手段：一是利用紫外／臭氧處理方法在合適條件下將石墨烯表面從疏水性轉(zhuǎn)變?yōu)橛H水性,從而使PEDOT:PSS水溶液能夠均勻地旋涂在石墨烯表面；二是在PEDOT:PSS水溶液中摻雜一定比例的表面活性劑(Zonyl)來改變PEDOT:PSS的潤濕性,使其能夠有效地在石墨烯表面均勻成膜。最后,從固-液接觸角理論出發(fā),提出了利用氧化鋅納米陣列對石墨烯與PEDOT:PSS的復(fù)合界面進行改性的想法并利用實驗加以驗證,該方法通過改變石墨烯表面的粗糙度進而能改變PEDOT.PSS溶液與石墨烯之間的接觸角。采用水熱法在石墨烯表面生長氧化鋅納米陣列,再利用掃描電子顯微鏡對該陣列薄膜的表面形貌和陣列結(jié)構(gòu)進行表征,最后將PEDOT:PSS溶液旋涂于該石墨烯片上以觀測二者的復(fù)合效果。
[Abstract]:Graphene is a kind of excellent optical, electrical, thermal, a new two-dimensional carbon material force performance, rapidly in recent years become the focus of research materials in the fields of graphene based electronic devices have attracted a lot of research. The graphene as electrode for organic solar cell because in the hydrophobic properties of graphene surface, PEDOT:PSS conductive polymer layer can not be covered uniformly on the surface of graphene, the two film, resulting in graphene organic solar cell electrode preparation. The low success rate from a better Shi Moxi will be used for this purpose in a solar cell, the main content of this paper including the following three parts: Shi Moxi growth on the surface of copper foil by chemical vapor deposition method to obtain high quality graphene by regulating some parameters, the metal substrate pretreatment process of growth of Shi Moxi The proposed method is simple and efficient process and graphene transfer steps in optimizing the growth process and the transfer process of graphene. The graphene and PEDOT:PSS compound into the problem of poor film, put forward two effective solutions: one is to use ultraviolet / ozone treatment method under suitable conditions on the surface graphene from hydrophobic to hydrophilic, so that the PEDOT:PSS solution can be uniformly spin coated on the surface of graphene; two is the surfactant in the aqueous solution of PEDOT:PSS doping proportion (Zonyl) to change the wettability of PEDOT:PSS, which can effectively on the surface of graphene film. Finally, starting from the solid-liquid contact angle theory, put forward by Zinc Oxide nano array composite interface of graphene and PEDOT:PSS modified the ideas and methods are verified by experiment, the method by changing the graphite Graphene surface roughness which can change between PEDOT.PSS solution and graphene by hydrothermal method. The contact angle on the surface of graphene growth Zinc Oxide nano array, then the surface morphology and structure of the array array films were characterized by scanning electron microscopy, the PEDOT: PSS solution was spin coated on the graphene sheet to composite effect observation of the two.
