摘要:

利用双光束干涉-无掩模光刻技术制备了周期性氧化石墨烯微结构阵列, 利用肼蒸气对氧化石墨烯脱氧还原, 然后蒸镀超薄Au薄膜制备了还原氧化石墨烯/Au复合微电极阵列(R-GO/Au). 对复合电极在可见光波段的透过率和表面电阻进行了表征, 结果表明, R-GO/Au复合微电极阵列具有良好的光电特性. 将R-GO/Au复合微电极阵列引入到有机太阳电池中作为半透明阳极, 器件的光电转化效率可达3.43%.

Abstract:

The reduced-graphene-oxide/Au(R-GO/Au) composite microelectrode array was fabricated by a simple method. The graphene oxide(GO) array was prepared by two beam interference-holographic lithography technique, and then reduced by hydrazine vapor to partially remove the oxygen-containing groups. Ultrathin Au film was deposited on the reduced-graphene-oxide(R-GO) array to improve its conductivity. The results indicate that R-GO/Au composite microelectrode array exhibits excellent surface morphology with precisely controlled period and high resolution, good transparency in visible light region and high conductivity. The organic photovoltaic device based on the R-GO/Au composite microelectrode array exhibits a high power conversion efficiency of 3.43%.

Key words: Reduced-graphene-oxide/Au composite electrode, Microelectrode array, Two beam interference-holographic lithography technique, Hydrazine vapor reduction
