Optical optimization of organic solar cell with bulk heterojunction

Opto-Electronics Review

Abstract

The work is devoted to the optimization of layer thickness in an organic photovoltaic cell. It presents the applied calculation method which is based on the optical transfer matrix 2×2 formalism. We present the influence of thickness of a PEDOT:PSS layer and of an active layer on the normalized modulus squared of optical electric fields distribution inside devices and on the distributions of exciton generation rate. We present the relationship between optimal thicknesses of the PEDOT:PSS layer and the active layer. We also present the influence of antireflection coating on distributions of optical electrical fields, as well as the distributions of exciton generation rate. Perpendicular and oblique illumination of the photovoltaic structure is discussed.
