dye sensitized solar cells applications of ruhemann’s purple metal complexes

Dye-sensitized solar cells (dsscs) represent a field of intensive study in recent years, focusing on the development of low-cost, environmentally friendly materials. the objective of this study is to produce environmentally friendly, low-cost dye-sensitized solar cells using amino acids. in this research study, the applications of the &ruhemann’s purple& compound, otherwise known as the glycine-ninhydrin test, which is used to determine the presence of amino acids, were carried out in dsscs. the formation and characterization of complexes of the glycine-ninhydrin compound with cu, fe, and co metals were conducted using uv-vis spectroscopy. in addition to the j-v curves, nyquist-type impedance curves were employed for the characterization of the prepared solar cells. the conversion efficiencies of the cu, fe, and co complex-based solar cells were found to be 0.36%, 0.26%, and 1.53%, respectively. furthermore, this study also involved the synthesis of tio₂ nanoparticles as dssc photoanodes via the hydrothermal method, along with xrd and fe-sem characterization. the results of this study indicate the potential for the use of glycine in dsscs, with promising implications for their future applications.
