Abstract

Herein, nanoparticles of zinc ferrite (ZnFe₂O₄) were initially synthesized by chemical co-precipitation method followed by ultrasonication. Then mixed with TiO₂ (P25), and subsequently used as photoanode for dye-sensitized solar cell. ZnFe₂O₄ nanocomposites were found to be active in the visible region of the solar spectrum, while P25 showed absorption in the UV region, demonstrating a possibility of wider absorption band and higher photoelectric conversion efficiency. Composite photanode (with 0.1 wt% ZnFe₂O₄) based cell showed high power conversion efficiency (PCE) of 4.55%, whereas, the PCE of the cell with pure TiO₂ as photoanode was 3.27%. Thus, there was an 39% enhancement of PCE for the composite photanode based cell.
