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.

• 结果表明在酸性介质中具有较大的开路光电位(V_(oc))；pH=2.；5时；空气气氛中V_(oc)值的大小顺序是ZnPc>MgPc>SnPc>PbPc>CoPc>FePc>VOPc>SiPcCl_2>AlPcCl>CrPc>CuPc>NiPc>GePcCl_2>MnPc
