Abstract

Dark IV is an important characteristic of a solar cell that mandates the open circuit voltage and fill factor of the device so a comprehensive simulation of photocurrent under applied voltage is not possible unless back injection of charged carriers at the donor-acceptor interfaces (the origin of dark current) are incorporated in the simulation. For the first time, this paper presents the simulation of dark and illuminated current in a polymer solar cell using Kinetic Monte Carlo approach.
