Cadmium indium selenide (n-CdIn sub(2)Se sub(4)) thin films have been synthesized by spraying the mixture of an equimolar solutions of cadmium chloride [CdCl sub(2)], indium trichloride [InCl sub(3)] and selenourea [(NH sub(2)) sub(2)CSe] in aqueous media onto preheated fluorine doped tin oxide (FTO) coated glass substrates at optimized parameters of substrate temperature and solution concentration. The photoelectrochemical (PEC) cell configuration of n-CdIn sub(2)Se/(l MNaOH + 1 MNa sub(2)S + 1 M S)/C has been used for investigating the current--voltage (I-V) characteristics under dark and white light illumination, photovoltaic output, spectral response, photovoltaic rise and decay characteristics. The PEC study reveals the thin film of CdIn sub(2)Se sub(4) exhibits n-type conductivity. The junction quality factor in dark (n sub(d)) and light (n sub(l)), series and shunt resistance (R sub(s) and R sub(sh)), fill factor (FF) and efficiency ( eta ) for the cell have been estimated. The observed efficiency and FF of PEC solar cell is found to be 1.95 and 0.37% respectively. Mott-Schottky plot shows the flat-band potential (V sub(fb)) of n-CdIn sub(2)Se sub(4)/(l M NaOH + 1 M Na sub(2)S + 1 M S)/C cell to be--0.655 V/SCE.
