【摘要】 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。更多还原

【Abstract】 The photovoltaic effect（PVE ） forheterojunction formed by C₇₀on GaAs electrode inthe photoelectrochemical cell was investigated.In fluences of various redox couples and of thicknessof C₇₀on the photovoltaic effect were observed. Theresults showed that:1)I₂/was the best redoxcouple in the photoelectrochemical cell.2)Thephotovoltaic property of C₇₀-GaAs electrode at 1μmfor thickness of C₇₀ was best.3 ) The photoelectricproperty of C₇₀ on GaAs electrode was excellent.更多还原
