摘要：

The temperature-dependent study of photocurrent of Al/chloropyll a/Ag cells has been carried out. The results show that the photocurrent (I(ph)), unlike dark current, shows an unusual behavior in that it increases as the temperature decreases. The striking feature is that I(ph) passes through a maximum and then decreases as the temperature is further decreased or increased. This is interpreted in terms of different efficiency of exciton dissociation into free charges at negatively charged traps associated with changes in microcrystalline structure of chlorophyll a with temperature.
