Abstract

In the process of solar energy conversion into electrical energy using the photoelectrochemical cell containing the sensitizer, rose bengal and supersensitizer. $I^-$, the photocurrent is stabilized and durable. But the long time span of irradiation causes the decrease of photocurrent monotonically. Spectroscopic and electrochemical analyses of rose bengal solution containing $I^-$ revealed that the decrease of concentration of rose bengal was attributed to the reaction of rose bengal in the dark with $I_2$ formed as a result of the possible photocatalytic reaction of rose bengal with $I^-$.
