Area of Science:

  • Materials Science
  • Renewable Energy
  • Nanotechnology

Background:

  • Dye-sensitized solar cells (DSSCs) show promise but haven't reached theoretical efficiency limits.
  • Improving device fabrication and interfacial engineering is critical for DSSC advancement.
  • Optimizing the dye-TiO2 nanoparticle interface is key to reducing charge recombination and enhancing light harvesting.

Purpose of the Study:

  • To develop a surface-coating adsorbent strategy for controlling the TiO2 nanoparticle interface.
  • To achieve the radiative limit of power conversion efficiency (PCE) in DSSCs.
  • To enhance light-harvesting properties and reduce charge recombination.

Main Methods:

  • Utilized 2-thiophenecarboxylic acid (THCA) and chenodeoxycholic acid (CDCA) as post-interfacial surface-coating adsorbents.
  • Engineered coadsorbent structure and optimized the TiO2 nanoparticle interface.
  • Implemented a monolayer adsorption process for improved surface coverage.

Main Results:

  • Achieved a PCE over 13.17% for a single porphyrin dye-based DSSC, the highest reported.
  • Demonstrated a PCE of 9.04% for a large-area DSSC (3 cm²).
  • Recorded a PCE of 11.16% for quasi-solid-state DSSCs with polymer gel electrolytes, showing 1000 h stability.

Conclusions:

  • Surface-coating adsorbents effectively control the TiO2 nanoparticle interface, enhancing PCE.
  • The developed method offers a practical approach to high-performance DSSCs.
  • These findings present viable alternatives to conventional power sources.
