摘要
报道了Ａｌ／α－ＳｎＰｃ／ＩＴＯ夹心结构的瞬态光电压随入射光强度和波长变化的演变特性和稳态连续光照射下的光电压作用光谱。稳态光电压作用光谱和其对应吸收光谱的变化趋势非常接近；而瞬态光电压的大小、极性和响应时间则共同取决于入射光的强度和波长。其中瞬态光电压的正峰部分（相对于ＩＴＯ电极）只在较强的光照射下才出现，而且其响应时间也总是慢于同一条件下出现的负电压峰。文中对该现象的内在机制作了初步的探讨。
The transient photovoltaic properties in the nanosecond region as the function of intensities and wavelengthes of incident light, as well as the spectral dependence of the CW photovoltaic response in Al/a SnPc/ITO sandwich cell have been reported. The CW photovoltaic action spectrum is similar to the absorption spectrum. The magnitude, polarity and response time of the transient photovoltage are found to be dependent on the intensity and wavelength of the incident light. The mechanism for this transient photovoltaic effects is briefly discussed.
