Interaction effects and performance of a photoelectric device — Marcel Dierl^1,2 and •Mario Einax^1,2 — ¹Institut für Physik, Technische Universität Ilmenau, 98684 Ilmenau, Germany — ²Fachbereich Physik, Universität Osnabrück, Barbarastraße 7, 49076 Osnabrück, Germany

We investigate a one-dimensional photoelectric device, where charge carriers interact via coupling constant V. Based on classical time-dependent density functional theory calculations, we find that nearest-neighbor interactions are of crucial importance for the current, the power as well as the efficiency of the nano-device. To point out the validity of this analytical approach, kinetic Monte Carlo simulations are performed.
