Abstract

We have grown organic solar cells through bilayer structure using copper phthalocyanine (CuPc) as the donor material and fullerene (C₇₀) as the acceptor. In this article, we demonstrate power conversion efficiency of 1.47% for the bilayered solar cells composed of CuPc and C₇₀. Successful tuning of the thickness of the individual layers was carried out to obtain the optimum solar cell parameters. It has been found that efficiency of the bilayer devices depends primarily on the individual layer thickness and thermal annealing of the devices. Overall, bilayer structure is suitable when the active layers are insoluble in most of the commonly available solvents.
