Abstract

In this article we have used an optoelectrical model to explore the behavior of the bulk heterojunction solar cells. Using a polar monolayer before the cathode, an internal electric field is set up inside the organic solar cell and it is justified that this electric field reduces the recombination rate. Increasing the active layer thickness enhances the carrier recombination because of their long path to the electrodes. We show that the electric field of this monolayer permits the increasing of the device thickness and improves light harvesting. Thus the electron–hole generation rate and the short circuit current enhances with the increased mobility and the resulting possibility of exciton dissociation. By increasing the open circuit voltage and the fill factor of the solar cell, this polar monolayer causes a significant efficiency improvement up to 30 %.
