Firstly, henna solution was prepared and characterized by FTIR spectrum. Using this solution containing lawsone, Pb(Law)2 and Cu(Law)2 complexes were synthesized and then these complexes were characterized by FTIR and mass spectra and elemental analysis. The henna solution and solutions of metal complexes dissolved in N,N-dimethylformamide (DMF) were used as interface layers in making three different photodiodes. Necessary graphs were drawn using the I–V, C–V, and (G/ω)–V measurement values taken for the photodiodes made and then the necessary parameters were calculated from these graphs. It was observed that Al/Pb(Law)2/p-Si photodiode was more ideal than Al/Henna/p-Si and Al/Cu(Law)2/p-Si photodiodes in the dark. Moreover, it was seen that as the illumination intensity increased, the Al/Pb(Law)2/p-Si and Al/Cu(Law)2/p-Si photodiodes moved away from ideality and that the Al/Pb(Law)2/p-Si photodiode was more ideal than the Al/Cu(Law)2/p-Si photodiode under all illumination intensities studied, provided that the illumination intensity was the same.
