Simulated Design and Improvement of Efficiency of Organic Solar Cells

AbstractWe have performed a program simulation for design and development of highly efficient organic solar cells. We have simulated a model cell structure of ITO (indium-tin-oxide) anode/CuPc (copper phthalocyanine)/C60 (fullerene)/BCP (2, 9-dimethyl-4.7-diphenyl-1, 10- phenanthroline)/A1 (aluminum) cathode. As a result, obtained short-circuit current density (Jsc), open-circuit voltage (Voc), values of fill factor (FF), and power conversion efficiency (η) are 2.25 mA/cm2, 0.442 V, and 0.35, 0.35%,. Also, Organic solar cells were manufactured with a condition obtained from simulation. Experimentally obtained values of Jsc, Voc, and n are 1.05 mA/cm2, 0.25 V, and 0.21 %, respectively. When compared experimental results with optimum simulation structure, the values of Jsc, Voc, and n are reduced by 53, 40, and 65 %, respectively.
