Photoelectric Property For C_(70) on GaAs Electrode

Abstract

在光电化学电池中测定C_(70)球烯在gAAS电极上所形成异质结的光伏效应,并研究不同介质电对和C_(70)薄膜厚度对光伏效应的影响。结果表明,1)I_2/是较佳的介质电对;2)C_(70)薄膜厚度约为1μM时光伏效应较大;3)C_(70)在gAAS电极上的光电性能是优良的。The photovoltaic eFFect(PVE ) Forheterojunction Formed by C_(70)on GaAs electrode inthe photoelectrochemical cell was investigated.In Fluences of various redox couples and of thicknessof C_(70)on the photovoltaic eFFect were observed.Theresults showed that:1)I_2/was the best redoxcouple in the photoelectrochemical cell.2)Thephotovoltaic property of C_(70)-GaAs electrode at 1μmFor thickness of C_(70) was best.3 ) The photoelectricproperty of C_(70) on GaAs electrode was excellent.国家自然科学基
