A comprehensive device modeling of solid-state dye-sensitized solar cell by MATLAB.

Dye-sensitized solar cell (DSSC) is technically and economically reliable alternative to the p-n junction photovoltaic devices. Recently, the energy conversion efficiency of DSSC has been reported to improve a lot using nanoporous electrode. Numerical modeling is effective strategies for depth understanding of the working mechanism of a solar cell. This paper illustrates the optimization of current density versus voltage (J-V) outcomes using MATLAB by varying the different physical parameter of DSSC like temperature (T), intensity(I), absorption coefficient (α) and thickness of electrode (d) in modeled simulation equation. Second order differential simulation equation has been used in present study for measurement of performance curve of Dye-sensitized solar cell. The current density versus voltage (J-V) curve for DSSC has also been calculated numerically using the internal variable such as diffusion coefficient (D), diffusion length (L), initial concentration of electrons (n0) and thickness of electrode (t). The current density versus voltage (J-V) curve. [ABSTRACT FROM AUTHOR]
