Abstract

The transport properties of cargo carriers for organic semiconductors depend on the presence and distribution of trap sites. As we know, traps are the result of irregularities in polymer molecules and chains caused by physical or chemical impurities in the structure of organic semiconductors. From the point of view of crystal defects that cause changes in energy levels and create energy gaps in band theory, the transport properties of cargo carriers in this type of systems will also undergo changes, the most important parameter of which is being replaced or trapped. Will be in the delivery process. Of course, defects can play a role in the distribution centers in the system.
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 momentum-diffusion equations and Poisson equation, as well as using different recombination models by finite element method.
