球烯C_（60）掺杂过渡金属酞菁配合物在GaAs电极上的光伏效应

Photovoltaic Effect of Fullerene-doped Phthalocyanine Complexes of Transition: Metals on GaAs Electrode

在光电化学电池中测定球烯Ｃ６０掺杂的过渡金属酞菁（ＭＰｃ）在ＧａＡｓ电极上所形成异质结的光伏效应，研究不同介质及不同过渡金属酞菁对光伏效应的影响．结果表明：１）Ｃ６０与ＭＰｃ在特定的有机溶剂中可形成新的加合物，以ＵＶ－Ｖｉｓｉｂｌｅ光谱表征，在长波部分有新峰出现；２）Ｃ６０掺杂增强了ＭＰｃ在ＧａＡｓ电极上的光伏效应．与ＧａＡｓ相比，△Ｖ可增强２～３倍；３）不同介质电对对光伏效应有较大的影响，Ｉ３／Ｉ是较好的介质电对．

The photovoltaic effects of 14 metallophthalocyanine complexes(MPc), Mg,Al,group 1VA and the 1st series of transition metals, in the electrolytic solutions are investigated, Influences of acidic or basic media and surrounding atmosphere (air,oxygen, nitrogen and hydrogen) on photovoltaic effect are observed. It has been shown that the open circuit photovoltage (Voc)in the acidic media are greater then those in the basic media. At pH 2,5 the Se quence of Voc in air is found to be:ZnPc>MgPc>SnPc>PbPc>CoPc>FePc> VOPc>SiPcCl2>AlPcCl>CrPc>CuPc>NiPc>GePcCl2>MnPc. The oxidizing atmosphere(O2)and the reducing atmosphere(H2)have greater influences on Voc. The order of Voc In different atmosphere is found to be: O2>air>N2>H2.
