Summary:
- This article discusses the development of a new type of 2D perovskite material that can be used to improve the efficiency of tandem solar cells.
- Tandem solar cells, which combine multiple light-absorbing layers, have the potential to be more efficient than traditional single-junction solar cells. The new 2D perovskite material can help boost the performance of these tandem cells.
- The researchers found that the symmetrical structure of the 2D perovskite material helps to improve the charge transport and stability of the solar cell, leading to higher overall efficiency.
