Thermal Perturbation in Dye-Sensitized Solar Cell

The impact of thermal activation in electron transport which incorporates as a perturbed term in recombination rate of electrons in Dye-sensitized solar cell (DSSC) is studied theoretically. This perturb term itself is non-linear and allows to increase the electron conduction significantly. The induced electron density due to this thermal activation is found to be dependent on initial conduction electron density and increases as the non-linear parameter beta increases upto certain value which is dependent on the parameter R (ratio of electron generation to trapped electron densities), and then decreases as beta increases. The electron lifetime and diffusion length are found to be functions of single parameter V/T which have two distinct and contrast behaviours with beta in electron transport.
