Area of Science:

  • Materials Science
  • Renewable Energy
  • Nanotechnology

Background:

  • Flexible perovskite solar cells offer advantages over rigid designs but face scalability challenges.
  • Current fabrication methods, like spin coating, are not suitable for large-scale production.
  • Printing electron transport layers (ETLs) is a key hurdle, with tin oxide (SnO2) being a common material.

Purpose of the Study:

  • To engineer a printable SnO2 ink for flexible perovskite solar cells using poly(acrylic acid) (PAA).
  • To enhance the coverage, morphology, and interface properties of printed ETLs.
  • To improve the efficiency, stability, and large-area printability of flexible perovskite solar cells.

Main Methods:

  • Introduction of PAA into SnO2 nanocrystal ink to improve dispersion and control solvent evaporation.
  • Engineering ink properties for optimized coverage and morphology of printed ETLs.
  • Modification of the buried interface to enhance charge transfer and reduce recombination.

Main Results:

  • Flexible devices achieved a high power conversion efficiency of 22.46% (certified 21.56%).
  • Devices demonstrated excellent stability, retaining 89.3% efficiency after 3000 bending cycles and 92.4% after 2000 hours of storage.
  • A large-area (30cm x 30cm) printed flexible module reached an efficiency of 16.40% (certified 16.28%).

Conclusions:

  • PAA-modified SnO2 inks enable scalable printing of high-performance flexible perovskite solar cells.
  • The engineered ink and interface modification significantly enhance device efficiency and operational stability.
  • This approach paves the way for the commercialization of large-area flexible perovskite solar modules.
