Popis: | 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 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, V fb ∼ − 0.275 V versus saturated calomel electrode (SCE), and a doping level density, N A ∼ 1.2 1016 cm−3, were determined. |
