During the last few decades, various types of solar cells have been invented, and huge research activities have been carried out to improve their power conversion efficiency (PCE). Bulk heterojunction (BHJ) organic solar cells (OSCs) have recently attracted the attention of numerous researchers because of their advantages such as light weight and low cost of fabrication processes. In this chapter, by analysing the influence of electric field component of the electromagnetic radiation propagating through the layered structure of BHJ OSCs and using contour plots of normalized modulus squared of the electric field, the constructive interference points (CIPs) which represent the positions of maximum absorption of photons and hence generation of charge carriers within the active layer are investigated for both the conventional and inverted OSCs.
