Abstract |
|
|
| Attempts have been made to enhance the conversion efficiency of photoelectrochemical cell using electrolytically deposited CdS semiconductor electrode in sulphide–polysulphide electrolyte. In the present investigation the thin film of polycrystalline CdS and mixed sulphide of Cd(II) and Bi(III) have been synthesised electrochemically onto conducting glass substrate by co-depositing one and both the metals and anodising the film in electrolyte bath containing aqueous solution of Na2S. The cell configuration is photoelectrode / NaOH (1M) + S (1M) + Na2S (1M) / Pt. The performance parameters of the cell include measurements of photocurrent, photovoltage, fill factor, cell efficiency, flat band potential, band gap energy, ideality factor, stability and study of I-V characteristics in dark. |
