The effect of recombination and density of charge carriers on Function of nanostructured polymer solar cells

In this paper, using different combinatorial models of carriers, the effects of basic parameters on the performance of heterogeneous organic solar cells as well as charge transfer are investigated. In order to simulate these processes, in this section, the basic parameters of P3HT: PCBM-structured organic solar cells have been studied by using the self-consistent solution of momentumdiffusion equations and Poisson equation, as well as using different recombination models by finite element method. In most of the proposed models and theoretical studies, the active region in organic solar cells is assumed to be inherent, while this assumption has drawbacks for studying and optimizing them, and the contribution of contaminating polymers should be considered for better study. To be taken. The studied structure is shown in Figure 3. This structure includes the active region with a mass structure of P3HT: PCBM with a thickness of 100 nm.
