Recently, a variety of conducting polymer have great potentials for practical utility. Among these polymers, polyaniline (polyaniline,PANI) has the widest applications .
Using electrochemical synthesis to fabricate Aniline copolymer has several kind of advantages (i) Aniline is cheap and easy to polymerize¡F (ii) High stability¡F(iii) The conductivity of the polymer can be modulated¡F(iv) The thickness of PANI film can be controlled. In conclusion, it is quite useful to apply the PANI into polymer solar cells as the hole transporting layer. We used Cyclic Voltammetry to grow the PANI thin film. Then, we investigated the performance of the device affected by morphology with different sweep rate and the difference of electric characteristic and transmission between PEDOT and PANI.
P3HT was used as a donor material because of its high stability and high absorption in visible light. PCBM was used as a acceptor material because of its high stability and high electron transportation. The device was constructed of ITO (150 nm) / PANI (50 nm) / P3HT:PCBM (100 nm) / Al (200 nm). When the sweep speed is lower, the particle of PANI thin film is closer and its scale size is more similar. When the sweep rate is 0.01 V/s, PANI thin film would grow about 80 nm, and the power conversion efficiency of 1.83% was achieved under AM1.5G 100mW/cm2 illumination.
