【Abstract】 The elementary photoeleotrochemical properties of liquid junction solar cells composed of N-CdTe film electrotrodes are reported in this paper. The cell oould be represented asN-CdTe/ 1M Na2S, 1M S. 1M NaOH/CThe electrode potential-current curves, voltage-current curves of the cells have been measured. The relationship between the irradiation intensity and the photovoltage, photocurrent and conversion eiEoienoy have been determined. Under the irradiation of 60mW/cm2, the energy conversion efficiency is 1~2%. The bandgap of the electrode is 1.43eV. The flatband potential of -1.1~-1.2V (VS·SCE)is determined by the measurement of the differential capacitance and the maximum open-circuit photopotential. Furthermore, the influence of the counter electrodes and electrolytes on the conversion efficiency have been tested.更多还原
