摘要/Abstract

摘要： 本文报道了由N-CdTe薄膜电极构成的液结太阳电池的基本光电化学性质.电池可表示为:
N-CdTe/1MNa₂S、1M NaOH、1MS/C
测量了电池的电流-电压、电流-电极电位曲线,确定了光强与光电压、光电流、转换效率的关系.在60mW/cm²光强下,电池的能量转换效率为1~2%.电极的禁带宽度为1.43eV,借微分电容及最大光电位的测定得到平带电位为-1.1~-1.2V (VS·SCE).此外,还试验了对电极与电解液对转换效率的影响.

Abstract: The elementary photoelectrochemical properties of liquid junction solar cells composed of N-CdTe film electrotrodes are reported in this paper. The cell could be represented as
N-CdTe/1M Na₂S, 1M S. 1M NaOH/C
The 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 efficiency have been determined. Under the irradiation of 60mW/cm², the energy conversion efficiency is 1~2%. The band gap 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.
