In recent years, there has been a rapid progress in the development of small-molecule organic photovoltaic cells with the power conversion efficiency reaching 12.0%. Besides high efficiency, the development of transparent conducting electrodes is of great importance for low cost and flexible organic solar cells. In this work, we have developed low-cost, efficient, semi-transparent small-molecule organic solar cells based on various alternative transparent electrodes, such as highly conductive polymers, ZnO, carbon nanotubes, doped C60, and conducting polymer/metal grid electrodes. These devices are carefully optimized by doping techniques for electrodes and interfacial layers. These results demonstrate that small-molecule organic solar cells based on alternative electrodes, optimized by doping technologies, have a promising future for practical applications in efficient, low-cost, flexible and semi-transparent device manufacturing. |
