Breakthrough in Perovskite Solar Cells Aims for Widespread Commercialization

Strategic Insights -

A team of researchers at the University of Louisville has made significant progress in developing a scalable and efficient method for producing perovskite solar cells, a promising alternative to traditional solar technologies. By combining classic roll-to-roll manufacturing with advanced annealing techniques, the team has achieved a power conversion efficiency of 16.7%, one of the highest recorded for perovskite solar cells on flexible substrates. This breakthrough has the potential to overcome significant technical challenges in the commercialization of perovskite solar cells, including stability, efficiency, and manufacturability.

Key Takeaways:

  • The researchers developed a mixed-cation perovskite ink with a robust coating window that addresses issues of stability and manufacturability for perovskite solar cells.
  • The team applied a classical roll-to-roll manufacturing perspective, utilizing compositional engineering and intense pulsed light (IPL) annealing to achieve a champion power conversion efficiency of 16.7%.
  • The processing time for the perovskite layer was significantly reduced, representing an advance toward the scaled production of perovskite solar cells on flexible substrates.
  • The research was supported by the United States Department of Energy (DOE) and has been peer-reviewed.
