Dye sensitized solar cells with chitosan and carboxy methyl cellulose gel electrolytes

Authors

Abstract

In this work, chitosan and carboxy methyl cellulose biopolymers were used as gelling agents in composition of electrolyte of dye sensitized solar cells. The effect of both biopolymers on performance of dye sensitized solar cell were investigated by adding the same amounts of two biopolymers to the liquid electrolytes composed of ox/red couple of I-/I3- with similar concentrations. The electrochemical Impedance spectroscopic studies and photovoltaic measurements showed the cell composed of carboxy methyl cellulose as gelling agent had more efficiency than the chitosan cell.
