Abstract : The work reports the effect of 80MeV 6+ Oxygen ion irradiation on the performance of DSSCs. TiO2 coated FTO were subjected to ion irradiation of fluences 1 × 1012 to 1 × 1014 ions/cm2. TiO2 coated FTOs were characterized with XRD for structural analysis and have shown anatase phase. Irradiated films were used as electrodes for DSSCs. We have observed that the irradiated light conversion efficiency of the cells was highest for fluence of 1 × 1013ions/cm2 and at the same fluence the cell parameters showed to be the best. The reason may be due to the surface modification of the TiO2 coated films due to irradiation. However lower fluences than 1 × 1013 ions/cm2 show less effect while higher fluence shown degrading effect on the cell performance which may be due to the worsening of contact between electrode and dyes. © 2017 Author(s).
