Abstract : Dye sensitized solar cells (DSSCs) using natural dyes are found to have moderate efficiency of energy conversion. In this work we address the energy conversion efficiency and stability of the DSSCs sensitized with natural dye namely Lawsone. Anchoring of the dye with the titanium dioxide is one of the factors which decides the efficiency and stability of the fabricated device. Lawsone ligand is synthesized first and then different metal complexes of Manganese, Zinc, Nickel, Cobalt, Copper, Iron and Chromium are attached to this ligand. DSSC’s are fabricated by sensitizing the titanium dioxide (TiO2) nano powder and nano fiber with the prepared Lawsone metal complex dyes. The device sensitized with Lawsone chromium metal complex shows increased efficiency and stability than the other DSSCs using simple natural dyes.
