Effectively reducing the voltage loss in organic solar cells (OSCs) is critical to improving the power conversion efficiency (PCE) of OSCs. In this study, highly efficient ternary OSCs were constructed by adding a non-fullerene acceptor Qx2 with a high open-circuit voltage (VOC) and low energy loss (Eloss) into PM6:m-BTP-PhC6 based binary devices.
In recent years, significant progress has been made in improving the performance and stability of organic solar cells, and there is ongoing research into new materials, device architectures, and manufacturing processes that could further enhance their efficiency and durability.
To augment the power conversion efficiency (PCE) of organic solar cells (OSCs), identifying an optimal donor/acceptor (D/A) blend is imperative to embody synergistic electronic, optical, and morphological characteristics.
In addition to morphological control and stability enhancement, there are several other performance optimization strategies for organic solar cells that have been explored in the literature. These strategies include the use of new materials, the optimization of device architecture, and the development of new processing techniques.
Improving the reproducibility of organic solar cells will require standardization of materials, device architectures, and testing methods. Addressing these challenges will require a multidisciplinary approach that brings together expertise in materials science, chemistry, physics, and engineering.
