叶绿素a、藏花红T双光敏体系光电池的研究

STUDY ON PHOTOVOLTAIC EFFECT OF DOUBLE PHOTOSENSITIVE SYSTEM IN CHLA AND SAFRANINE T

本文研究了叶绿素a和藏花红T组成的光电化学电池．报道了电池的光电特性．发现藏花红T对电池的开路电压和短路电流有很大影响．较纯粹的叶绿素光电池开路电压增大6～8倍，短路电流提高2～3个数量级，光电转换效率达10－3％．分析了光电池光电效应增加的原因．

A photoelectrochemical cell formed by Chla and Safranice T (ST) has been studiedin this work. The photovoltaic characters of the cell were reported. The results indicatethat ST has a great effect on the Voc and Isc of the cell. Voc and Isc of the cell are 6 to8 times and 2 to 3 times higher respectively than without ST. Power conversion efficiency was above 10-3%. The mechanism of photovoltaic effect of the cell was discussed.
