Plastic electronic devices can be used to emit light, or can convert sunlight into electricity. Charge transport in plastic electronic devices is described by thermally activated hopping of electrons between sites with varying energy levels. Since the hopping mechanism is hard to describe analytically, numerical computer simulations are often used to perform this task. These simulations provide new insight in the role of individual hops when considering the overall performance of plastic devices. This thesis discussed different topics concerning charge transport simulations. First, the impact of a relatively new hopping rate equation is investiged for devices with small amounts of free charge carriers. Next, a new method for performing numerical charge transport simulations using GPU's is explained. This new method is then used to investigate the validity of utilizing steady-state transport phenomena for the describing plastic electronics. Finally, the malicious extraction of charge carriers at the contacts of a plastic solar is investigated numerically, and it is found that the corresponding loss is efficiency is small.
