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… More >
