Boosting Solar Cells with Smart Molecules

Tue Jul 15 2025

Scientists have found a way to make solar cells more efficient and stable.

Multitasking Molecules

  • Special molecules added between layers of solar cells.
  • Functions:
  • Align energy levels.
  • Reduce defects.
  • Protect from moisture and other issues.

Beyond Simple Molecules

  • Traditional solar cells use simple molecules for energy movement.
  • New molecules are multitaskers:
  • Improve energy movement.
  • Increase durability.

Real-World Performance

  • Test Results:
  • Worked better and lasted longer.
  • Withstood high humidity and heat for over 1000 hours.
  • No protective coatings needed.

Simple and Practical

  • Improvements made using simple methods.
  • Easier for others to adopt this technology.
  • A step forward in making solar cells more practical and reliable.

questions

    Could the dramatic improvement in PSC performance with FDI be a result of undisclosed proprietary technology rather than the claimed functional enhancements?
    What are the primary mechanisms by which the FDI enhances the moisture resistance of perovskite solar cells?
    What are the potential trade-offs between the enhanced performance and the increased complexity of incorporating FDI into PSCs?
