Determination of the optimal bandgap of a polymer in bulk heterojunction solar cells

The aim of this paper is to determine the optimal bandgap of a polymer used as a photo- active material in bulk heterojunction solar cells in order to maximize the power conversion efficiency of the device. We have considered an ideal absorption profile for the photoactive material and we calculat...
