| 摘 要： | 用卤化法将噻－２＇－菁光敏染料共价键合于单晶硅表面。测定了键合染料硅片的表面光电压，结果表明，键合光敏染料噻－２＇－菁对单晶硅具有很强的敏化作用；利用电化学测量和紫外可见吸收光谱确定了键合光敏染料噻－２＇－菁与硅之间的相对能级位置，并对界面电子转移过程进行了讨论。

| Abstract: | The thia-2'-cyanine was bonded covalently onto monocrystalline silicon surface through halogenation way.The measurement of surface photovoltage of dye-bonded silicon wafer indicates that there is a great sensitization of the dye to the silicon.The relative energy level between thia-2'-cyanine and silicon was determined by UV-VIS and electrochemistry techniques.The interfacial charge transfer process was also discussed. |
