RETRACTED: Enhanced Photovoltaic Performance of the Dye Sensitized Solar Cell Using Natural Dyes with Surface Modification of the Photoanode

Retracted:

The paper has been retracted upon authors' request.
The authors suspect that the results reported in the work were affected by an honest error. An attempt to reproduce the results of the work failed. The authors are not able to reproduce the microstructure of the CaCO₃ coated with TiO₂ and the high-resolution images of the samples created as part of this work. The authors are going to verify the characterization data i.e. XRD pattern and absorption spectra.

Abstract:

The efficiency of the best Dye sensitized solar cell is primarily depends on the good light harvesting property of the photo anode. Present study uses Lawsone (2 hydroxy [1, -naphthoquinone), the natural dye and compare the performance of photo anode in bare TiO₂ and with nanoporous CaCO₃ coated TiO₂. As compared to bare TiO₂, the surface area of nanoporous CaCO₃-coated TiO₂ increases, consequently, a better amount of dye adsorption occurs. The coating of CaCO₃ increases the impedance at TiO₂/dye/electrolyte interface and affect lifetime of the photoelectrons. Due to this reasons the short circuit current Jsc, open-circuit voltage (Voc), and fill factor (FF) increases. Thereby, the energy conversion efficiency of the solar cell is improved.
