Abstract

In recent years organic solar cells have been recognized to have tremendous potential as alternatives to their inorganic counterparts, because they have many distinctive features such as they are flexible, colorful, have a lightweight and they are environmentally friendly. They have the ability to produce the cheapest electricity due to their low costs and be competitive with the silicon solar cells. Furthermore, the number of benefits of organic solar cells is expected to increase greatly as the technology is further developed. However, they have some obstacles and challenges to be utilized commercially on a large scale have been highlighted by their relatively low power conversion efficiencies and the relatively short device lifetime. Despite these challenges, the tunability and versatility of organic materials offer promise for future success. The evolution of the organic solar cells׳ performance over time has been addressed in this work, the present study provide the differences between organic and silicon solar cells which reveal the challenges that affect the development of organic solar cells efficiencies. In addition, it shows the historical development of efficiency of the organic solar cells in each generation: (i) single layer organic solar cells, (ii) donor-acceptor bilayer heterojunction organic solar cells and (iii) bulk heterojunction organic solar cells. Finally, the paper concludes by suggesting that future research should focus on addressing the identified challenges and developing new materials and technologies that can further improve the performance and efficiency of organic solar cells.
