Abstract
The photoelectrochemical behaviour of n-InSe single crystals in aqueous solutions has been studied in the presence and absence of several redox systems. Among them, Ce3+/4+ and KI/I2 yielded the highest photocurrents, photovoltages and show the highest stability. The semiconductor energy gap Eg = 1.2 eV, has been calculated from transmittance measurements. The flat band potential UFB = -0.40 V vs NHE and the donor density have been calculated from differential capacity measurements.
