This $411,601 federal project grant awarded by the National Science Foundation's Engineering program (CFDA 47.041) aims to conduct fundamental research to enhance the performance and stability of tin perovskite solar cells. The key products and services to be delivered under this 3-year grant, awarded on October 1, 2024, are:

  1. Developing novel self-assembled monolayers as the bottom contact for tin perovskite solar cells to reduce defect density at the interface and improve open-circuit voltage.
  2. Designing and applying passivation molecules as top surface termination to promote favorable band bending and enhance electron transport.
  3. Implementing resonant nanostructures on the tin perovskite film surface to increase photon harvesting and short-circuit current density.

This research project at Cornell University seeks to advance the fundamental understanding of tin perovskite materials and device physics, which could lead to transformative improvements in clean energy technology. The work will also provide valuable training opportunities for graduate and undergraduate students, particularly from underrepresented groups, and engage the local community through STEM outreach activities.
