Abstract
Metals (Pt, Pd) loaded polyaniline nanofibers (PANI NFs) were synthesized by the interfacial polymerization and applied as counter electrodes for dye sensitized solar cells (DSSCs). The Pt metals were uniformly decorated on the surface of PANI NFs which increased the diameter of the fibers by ∼80-100 nm. The surface properties revealed that the metallic Pt and Pd were distributed on the surface of Pt-PANI NFs and Pd-PANI NFs respectively. By cyclovoltametry studies, due to the incorporation of Pt and Pd metals into PANI NFs, the electrocatalytic activity was improved towards the reduction of I-3 ions in the redox electrolyte. The superior electrocatalytic activity of Pt-PANI NFs counter electrode inferred the high conversion efficiency (∼6.9%) of DSSC than that of DSSC with Pd-PANI NFs (∼5.2%) counter electrode. Considerably, the DSSC with Pt-PANI NFs CE exhibited significantly the improved photovoltaic performance by ∼40% and ∼25% as compared to DSSC with PANI NFs and Pd-PANI NFs CE respectively.
