Brilliant Cresyl Blue - Fructose for enhancement of solar energy conversion and storage capacity of photogalvanic solar cells

The Brilliant Cresyl Blue dye as photosensitizer, Fructose as reductant and NaOH as alkaline medium have been studied for enhancing the solar energy conversion and storage capacity of the photogalvanic solar cells. In this study, the observed values of electrical parameters like maximum potential, maximum photocurrent, short-circuit current, power at power point, and conversion efficiency are 1115 mV, 785 mu A, 590 mu A, 183.3 mu W, and 1.9586%, respectively. In dark, the cell performance in terms of storage capacity ( as half change time) was 228 min. The obtained results are highly encouraging as they are radically higher than results reported so far in the field of photogalvanics. We conclude that Brilliant Cresyl Blue - Fructose system significantly enhances the performance of the photogalvanic solar cells and this system may be the basis for further advancement of this technology.
