The Gouy-Chapman capacitor of double layer in Dye Sensitized Solar Cells: Study and simulation

ATOUANI Toufik

Abstract


Since their creation in 1991 by Prof. Graezel and his research group, Dye Sensitized Solar Cells (DSSC) have attracted great interests.  In the course of the years, this type of solar cells has shown a great development potential allowed to achieve an energy efficiency of 14%.

Most parts of the photovoltaic effect phenomena involved in the DSSC  (the light absorption, the creation and separation of charge carriers) are located in the active layer that extends from 10 µm to 20 µm  from the  electrode. The oxidized mediator () in the electrolyte is transported to the counter electrode where their regeneration occurs by the electrons through the external circuit. The charge carriers transfer is influenced by the double layer which is created at the electrolyte/metal contact. This phenomenon was neglected in most previous studies. This contact will help create the Gauy-Chapman capacitor (Cgc).

 The Cgc capacity is proportional to the ions’ concentration in the electrolyte. The aims of this  work is to study the influence of the capacitor and the influence of periodic disturbances of luminous flux -caused by periodic shading-  on the I–V curve of the DSSC cell. The maximum power point improves for relatively high values of Cgc capacitor (100uF, 10uF 1uF). The deterioration of the I–V curve takes considerable effect for frequencies above 0.03 Hz.
