【摘要】 作为染料敏化太阳能电池的一个重要组成部分,对电极的研究对染料敏化太阳能电池(DSSC)的发展有着重要的意义。石墨烯基材料因其良好的电化学催化活性,高的电导率、腐蚀阻抗,大比表面积、重量轻以及低制备成本而受到了研究人员的关注。本文选用还原氧化石墨烯与聚苯胺复合作为对电极进行研究,通过石墨烯的高电导率以及聚苯胺较好的催化活性能够制备出了性能更优越的复合对电极。并对其进行了XRD、SEM表征以及电化学性能测试,探究了其作为染料敏化太阳能电池对电极的光电转换效率。更多还原

【Abstract】 As an important part of dye-sensitized solar cells, the study of electrodes has important implications for the development of dye-sensitized solar cells(DSSCs). Graphene-based materials have good electrochemical catalytic activity, high electrical conductivity, corrosion resistance, large specific surface area, light weight, and low preparation cost. Graphene-based materials have attracted the attention of researchers. In this paper, the combination of reduced graphene oxide and polyaniline was used as the counter electrode. Through the high conductivity of graphene and the better catalytic activity of polyaniline, the composite counter electrode with better performance can be prepared. The XRD, SEM and electrochemical properties of the composite counter electrode were tested. We investigated the photoelectric conversion efficiency of graphene oxide and polyaniline as DSSC counter electrode.更多还原
