摘要
在光电化学电池(PEC)中分别测定了6种典型的金属酞菁配合物(MPc)在GaAs单晶电极上所形成的异质结的光伏效应,并研究了不同介质电对及介质溶液的酸碱性对光伏效应的影响,结果表明:O_2/H_2O(KCl溶液)及l_2/l^-_3是两种较好的电池介质电对;介质溶液酸碱性的改变对金属酞菁配合物的光伏效应有较大的影响;6种金属酞菁配合物中ZnPc、MgPc具有较好的光伏效应。
In the photoelectrochemical cells (PEC), the photovoltaic effects of six typical metallophthalocyanine complexes (MPc) on GaAs single crystal electrode forming heterojunction were inves ted, respectively. Influences of various redox couples and medium acidity-basicity on the photovoltaic effects were studied. The results have shown that: 1)O2/H2O(KCl) and I2/I3- are two kinds of better redox couples in the cells. 2) the changes of medium acidity-basicity have greater inflcences on the photovoltaic effects of MPc. 3)ZnPc and MgPc possess better photovoltaic properties than the others among the six metallophthalocyanine complexes.
