Molecular Bridge Boosts Perovskite Solar Cells

• A research team has proposed a novel strategy to enhance the performance of perovskite solar cells; using a molecular bridge made of ammonium cations to create a strong connection between layers. Theoretical and experimental studies show promise for top-performing solar cells, with potential for clean energy generation.

A research team from the Institute of Solid-State Physics, Hefei Institutes of Physical Science of the Chinese Academy of Sciences proposed a novel strategy to enhance the performance of perovskite solar cells. This strategy involves the use of a molecular bridge made of ammonium cations to create a strong connection between different layers of the solar cell. Theoretical analyses and experimental results showed that the robust bottom interface improved the extraction and transport of photo-generated carriers, enhancing overall device performance. This molecular bridge strategy promises to propel the development of top-performing perovskite solar cells, offering a potential direction towards commercialization for clean energy generation.
