Overview

Demonstrates enhanced device performance in perovskite solar cells, suggesting improvements in stability and efficiency.

Key Points

  • The research aims to improve the crystallization process and device performance of antisolvent-free perovskite solar cells.
  • Proposed a transient interphase strategy to control nucleation and crystal growth.
  • Used tetramethylurea to induce nucleation and form a Cs-rich interphase.
  • Assessed the performance of perovskite solar cells with the new crystallization approach.
  • Achieved device efficiency of up to 25.63% and module efficiency of 19.62%.
  • Demonstrated negligible degradation after 1700 hours under stability testing.
  • Maintained 90% of initial efficiency after 3500 hours, indicating exceptional stability.
