四苯基卟啉(TPP)涂于导电玻璃形成半透明分子固体光电极。因而亦可构成多层液体接界光伏打电池而取得高的光电势或光电流。这就与植物叶绿体的基粒有类似处,显示可从多方面模拟光合作用。本文用此种电极做出H-TPP与各种M-TPP光电极光伏打效应的对比研究,其中M为Mg,Mn,Fe,Co,Ni,Cu或Zn等金属。结果显示,可见光下红、绿光区分子吸收很弱的Q带,在光电极工作光谱中成为很强的可与蓝光区相比拟的谱带,这在M-TPP较H-TPP尤为突出;并得到TPP中心原子不同时的两组各平行于电负性的光伏打效应序列;及界面电解质特性吸附导致的双电层效应。
Tetraphenylporphyrin (TPP) is applied to the conductive glass to form a translucent molecular solid photoelectrode. Which can also form a multi-layer liquid junction photovoltaic cells and obtain high photoelectric potential or photocurrent. This is similar to the grana of plant chloroplasts and shows that photosynthesis can be mimicked in many ways. In this paper, a comparative study of the photovoltaic effect of H-TPP and various M-TPP photoelectrodes was made using this electrode, where M is a metal such as Mg, Mn, Fe, Co, Ni, Cu or Zn. The results show that the Q-band which is weakly absorbed by the red and green light in visible light becomes a strong band comparable to the blue light in the working electrode of the photoelectrode, which is more prominent than H-TPP in M-TPP; And two groups of PV strike sequences parallel to electronegativity at different TPP center atoms are obtained. The double layer effect due to the adsorption of interface electrolyte is also obtained.
