Abstract

In this study, we designed a highly efficient ITO/PEDOT:PSS/P3HT:PCBM/Al-based bulk heterojunction organic solar cell. We investigated the performance of various optical and electrical properties of the designed organic solar cells. We improved the power conversion efficiency by using appropriate materials in different layers of the organic solar cells and refractive index and lattice constant matching among the layers. GPVDM simulator was used for simulating various properties of the organic solar cells, such as current density, voltage density, fill factor, and power conversion efficiency. Various parameters of the active layer of the organic solar cells were varied for optimization. In addition, we analyzed the impact of the thickness of the active layer and device series resistance on the improvement of the power conversion efficiency of the organic solar cells. Maximum power conversion efficiency of 16.46% with a fill factor of 74.09% was obtained for a series resistance of 15 ohms. We observed an inversely proportional relationship between power conversion efficiency and series resistance. We optimized the value of the thickness of the active layer as 75 nm while designing the organic solar cells to achieve maximum power conversion efficiency. We strongly believe that the proposed organic solar cell model will play a significant role in achieving high PCE organic solar cells.
