Abstract: The work that is presented here is focused on the results that were obtained during studies of the performance of the DSC under certain reverse bias conditions. When one cell in the series connection in a module is shaded, the current will pass this cell in reverse bias. Although the work is focussed on the chemical stability of the dye, various techniques were employed to determine the physical changes in the cell. This presentation shows how electrochemical and impedance measurements (Nyquist and Bode plots and IV curve data) can compliment spectroscopic measurements (FTIR, Raman, UV-vis) to characterise a dye solar cell.
