Abstract

The article brings out the need for switching onto Dye Sensitized Solar Cells (DSSCs) over traditional solid state solar cells. It also features several different equivalent circuit models for DSSC reported by various research groups based on Electrochemical Impedance Spectroscopy (EIS). By listing these equivalent circuits, the article tries to make out the difference in the equivalent circuits of the traditional solid state solar cells and DSSCs. Since the principle and working mechanism of the traditional solid state solar cells and DSSCs are different, the equivalent circuit models for the two cannot be the same. They differ with each other in various circuit parameters and when operated in high frequency range. EIS is a powerful technique to study the kinetics of electrochemical and photoelectrochemical processes taking place inside the cell. So EIS is used by the researchers to model the equivalent circuits for DSSCs. Based on the comparison between various models featured, the article lists those parameters of the cell which have to be optimized and taken care of before making a cell for getting maximum efficiency.
