Abstract

Four numerical schemes are introduced for the analysis of photocurrent transients in organic photovoltaic devices. The mathematical model for organic polymer solar cells contains a nonlinear diffusion–reaction partial differential equation system with electrostatic convection attached to a kinetic ordinary differential equation. To solve the problem, Polynomial-based differential quadrature, Sinc, and Discrete singular convolution are combined with block marching techniques. These schemes are employed to reduce the problem to a nonlinear algebraic system. The iterative quadrature technique is used to solve the reduced problem. The obtained results agreed with the previous exact one and the finite element method. Further, the effects of different times, different mobilities, different densities, different geminate pair distances, different geminate recombination rate constants, different generation efficiencies, and supporting conditions on photocurrent have been analyzed. The novelty of this paper is that these schemes for photocurrent transients in organic polymer solar cells have never been presented before, so the results may be useful for improving the performance of solar cells.
