Effect of Material Parameters on the Optical Properties of Dye-Sensitized Solar Cell Photoanode

Abstract:

The presented theoretical analysis predicts the behaviour of optical properties of film with regards to materialistic parameters of the photoanode of dye-sensitized solar cell using the theory of dispersive transport. The porous nature of photoanode is considered for the simulation task. The variations in refractive index and absorption index of the semiconductor film with change in the values of thickness and porosity are studied by using finite element method. The theoretically demonstrates that refractive index increases with the increase in thickness and decreases with increase in porosity but absorption index shows a monotonic behaviour.
