Area of Science:

  • Organic photovoltaics
  • Materials science
  • Polymer chemistry

Background:

  • All-polymer solar cells (all-PSCs) are promising for flexible electronics.
  • Current all-PSCs have lower power conversion efficiencies (PCEs) than small-molecule-acceptor devices due to poor morphology and crystallinity.
  • Conventional thermal annealing (TA) offers limited control over polymer acceptor crystallization and vertical distribution.

Purpose of the Study:

  • To develop an innovative wet-assisted annealing (WAA) strategy for all-polymer solar cells.
  • To overcome the limitations of conventional thermal annealing in controlling morphology and crystallinity.
  • To enhance the performance and stability of all-polymer solar cells.

Main Methods:

  • Developed a wet-assisted annealing (WAA) strategy utilizing selective dissolution and volatilization of assist solvents.
  • Applied WAA during the thermal annealing process to optimize donor and acceptor vertical distribution in bulk heterojunction (BHJ) structures.
  • Investigated the impact of WAA on molecular stacking and morphology of polymer acceptors.

Main Results:

  • WAA finely optimized the vertical distribution of donors and acceptors in BHJ structures.
  • The strategy significantly enhanced polymer acceptor molecular stacking, leading to a well-defined fibrillar network morphology.
  • PM6:PY-DT-based binary all-PSCs processed with WAA achieved a record power conversion efficiency (PCE) of 20.04% with improved stability.
  • WAA demonstrated consistent performance across different batches of polymer acceptors, highlighting its robustness.

Conclusions:

  • The WAA strategy is a robust and practical approach for fabricating high-efficiency and stable all-polymer solar cells.
  • WAA effectively addresses the morphological and crystallinity challenges in all-polymer systems.
  • This method significantly advances the performance of flexible and portable photovoltaic devices.
