Abstract: | The transient processes in photogalvanic cells using the *Ru(bipy)32++Fe3+→Ru(bipy)33++Fe2+ system are investigated by measurement of the current-time and the potential-time characteristics. Under conditions of high light intensity and low to medium workloads of the cell, a pronounced maximum in the voltage-time curve is observed. This maximum appears after some milliseconds and it amounts to four times the stationary value. The experimental results are explained and the transients simulated, using the theoretical model developed in Part I of this series. |
