Alternative Energy Physics Solar Cell Monte Carlo event driven Organic The generation of photocurrent in organic solar cells starts with a photon being absorbed in the active layer and creating an excited electron/hole pair (exciton). The exciton is mobile and dissociates into electron and hole at an interface between donor and acceptor material, unless it decays before it reaches the interface. If they do not recombine, the charge carriers migrate toward the appropriate electrode and contribute to the photocurrent. Thus, the efficiency of organic solar cells depends strongly on the geometry and electronic properties of the donor/acceptor materials. Simulating in detail the processes described above is of interest since it enables the modeling of devices with dierent architectures and materials properties. Since processes such as exciton absorption, electron hopping, and recombination take place on vastly dierent time scales, we employ an event-driven Monte Carlo algorithm to simulate a coarse grained lattice model of the active layer of organic solar cells. We investigate devices of two geometries, one planar and one V-shaped, that differ significantly in the size of the donor/acceptor interface. The trends observed in our results agree with literature ndings that show that, as the interface area increases, the current density, charge carrier density and internal quantum efficiency of the device also increase. 2011-08-15 English text University of Akron / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=akron1311812696 http://rave.ohiolink.edu/etdc/view?acc_num=akron1311812696 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
