✦ Synopsis

The photoelectrochemical response of electrodeposited p-CulnSe2 thin films from sulfate bath and different citrate ion concentrations is reported. The best cathodic photoresponse was obtained with thin films deposited in 0.06 M sodium citrate. The film characteristics show a preferred orientation with (1 1 2) direction and sphalerite structure. Dark capacitance measurements in 0.5 M H2SO4 solution at 50 KHz showed a linear behaviour from which flat band potential, Vfb ,-~ --0.275 V versus saturated calomel electrode (SCE), and a doping level density, NA ~ 1.2 1016 cm-3, were determined.
