Exact Analytical Analysis of Dye-Sensitized Solar Cell: Improved Method and Comparative Study

Dye sensitized solar cell (DSSC) being one of the main focus in area of photovoltaic after silicon solar cell, modeling and estimating their parameters becomes important for their analysis and enhancement in their performance. We have proposed an analytical approach having no approximation for extracting various parameters of DSSC using a well known Lambert W-function technique. The model used in present work is single diode model where effect of capacitance and inductance has been neglected. We have applied our method to six different DSSCs, which were previously reported in literature for both treated (Carboxylic acid treatment) as well as non treated solar cell. Plots of various parameters including I-V relations of different solar cells are presented in this article. To validate the present method proposed in extracted parameters are compared with those present in literature. The results thus obtained demonstrate that this method proves to be superior to available methods and can be extensively applied for analyzing dye sensitized solar cells.
