Overview

Randomized trial demonstrates enhanced crystallization and efficiency in perovskite-silicon tandem solar cells, implying improved energy outcomes.

Key Points

  • This research aims to enhance the growth and quality of perovskite films on textured silicon for improved solar cell efficiency and stability.
  • Introduced a healing intervention using MASCN solution on perovskite films to promote secondary crystal growth.
  • Applied hybrid two-step deposition methods combining co-evaporation with solution processing.
  • Evaluated tandem solar cells with reported efficiency and stability under continuous illumination.
  • Achieved a champion efficiency of 21.1% for wide-bandgap perovskite solar cells (1.68 eV).
  • Obtained a certified stabilized tandem efficiency of 30.77% with a Voc of 1.915 V over an active area of 1.164 cm².
  • Demonstrated that the encapsulated device maintained performance after 3400 hours of continuous monitoring.
