Author(s): R. C. Meena, Vijay Kumar and Gautam Singh

The photovoltages developed in system consisting of thymole blue as photosensitizer and ascorbic acid as reducing agent. The photopotential and photocurrent generated by this cell were 810.00 mV and 150.0 μA, respectively. The observed conversion efficiency was 0.8038% and the maximum power of cell was 82.06 μW. The storage capacity of the cell was 54.00 minutes in dark. The effects of different parameters on electrical output of the cell were observed and a mechanism has also been proposed for the generation of photocurrent in photogalvanic cell.
