Abstract:
A claylike conductive material comprising polyaniline (PANI)acetylen e black particles is fabricated as a hole conductor for dye sensitiz ed solar cell (DSSC). The results show that the introduction of acetylene black into the polymer electrolyte improves the photovoltaic behavior of solidstate DSSC, owing to the increase of the hole mobility of PANI electroly t e, the improvement of the wetting quality of the composite electrolyte, and the reinforcement of interface contact between electrode and the electrolyte. Final ly, the overall energy conversion efficiency of DSSC with PANI50％(in weight) a cetylene black electrolyte is 48％ of that of liquid DSSC. Therefore, the PANI a cetylene black composition is a credible alternative to hole conductor in ap plication of solid DSSC.
