In last decade, organic solar cell (OSC) has attracted many attentions due to its special advantages such as low cost, easy large scale fabrication and high flexibility. However, the stylish OSC anode Indium Tin Oxide (ITO) is not flexible and would undergo breakdown on bending of flexible substrates. What’s more, ITO is costly since the limited indium in the nature. Recently, carbon nanotubes (CNTs) film shows potential to alternate ITO as high performance flexible anode since its ability to surmount these constrains and similar work function with ITO. Nevertheless the conductivity and transparence of CNTs film are still far below its counterpart. Additionally, a dependable model of OSC with CNTs film anode is not well established. In this paper, transparent conductive CNTs film is prepared on glass and plastic substrates at first. A facile filtration and pressing fabrication method is introduced. Our empirical model shows that dimension of CNTs bundles has significant effect on CNT network performance. FTIR shows the post-treatment effect on CNTs film. The OSC with high performance CNTs film anode shows similar efficiency compared with regular OSC with ITO anode.
