(a) MS plot obtained for TO1 sample; (b) Dependence of the open-circuit potential on the light intensity (OCP method) in pure electrolyte (full symbols) and with the addition of ethanol (empty symbols). The errors in determining potentials are ± 15 mV for all samples; (c) POP method for TO1 sample in pure electrolyte; (d) Potential values of the conduction band (CB), calculated valence band (VB) and potential levels, obtained by POP and OCP methods in pure electrolyte and with the addition of ethanol (Et).
