Nature Communications 12, Article number: 178 (2021) Cite this article Tandem organic solar cells are based on the device structure monolithically connecting two solar cells to broaden overall absorption spectrum and utilize the photon energy more efficiently.
In the field of organic photovoltaics, the power conversion efficiency of single junction solar cells continues to improve. However, tandem organic solar cells are poised to push the efficiency limits even further and offer a promising avenue for improving the performance of organic photovoltaic devices.
The growth of InO perovskite–organic tandem solar cells 3, has not yet been demonstrated. or high carrier density 2D materials 131. In these devices, the organic bulk heterojunction is positioned directly on top of the perovskite material (Fig. 5a).
The homojunction tandem organic solar cell is a prototypical organic tandem structure designed to boost the efficiency of a single device by improving absorption and charge extraction .
Here are some potential future developments and trends for organic solar cells : 1. Tandem cells: Tandem solar cells, which combine multiple layers of different materials to capture a wider range of the solar spectrum, have shown great promise in improving the efficiency of organic solar cells.
