Optical properties of iodine-based electrolyte used in bifacial dye-sensitized solar cells

Abstract As third-generation solar cells, dye-sensitized cells (DSSCs) can show bifacial harvesting capabilities by utilizing transparent conducting oxides as a counter electrode. Herein, the electrolyte is considered critical layer from optical perspective. In this paper, an attempt to estimate properties of Iodine-based electrolytes, typically used in demonstrated. The refractive index for effective medium calculated be 1.4535 ± 0.005 thin film 33.4 0.5 μm thickness, using near-infrared Fabry–Perot resonances. extinction (absorption and scattering) dispersion spectra prepared were fitted Lorentz–Dude (LD) model. Finally, utility extracted parameters was examined through finite difference time domain solver, Massachusetts Institute Technology Electromagnetic Equation Propagation. simulated transmission spectrum perfectly agreed with measured less than 0.1% root–mean–square error. demonstrated accurately DSSCs fabrication may impacted theoreticians who are interested optoelectronic modelling such electrochemical well those dealing devices informatics.
