Area of Science:

  • Materials Science
  • Renewable Energy
  • Nanotechnology

Background:

  • Low charge carrier mobility in polymer solar cells (PSCs) limits power conversion efficiency (PCE).
  • Incorporating high-mobility additives is a key strategy to enhance PSC performance.
  • Two-dimensional (2D) Bismuth Oxy-Selenide (Bi2O2Se) offers ultrahigh mobility and thermal stability, making it a promising additive.

Purpose of the Study:

  • To investigate the effect of 2D Bi2O2Se nanoflakes as an additive in PSCs.
  • To enhance charge transport, morphology, and ultimately the PCE of PSCs.
  • To explore the potential of Bi2O2Se in photovoltaic applications.

Main Methods:

  • Fabrication of few-layer 2D Bi2O2Se nanoflakes using lithium intercalation and shear force-assisted liquid phase exfoliation.
  • Introduction of Bi2O2Se nanoflakes as an additive into the active layer of PSCs.
  • Characterization of device performance (PCE) and stability for different PSC formulations.

Main Results:

  • Bi2O2Se nanoflakes improved donor-acceptor interfaces, charge transfer pathways, and film crystallization, forming continuous networks.
  • PCE increased from 10.09% to 12.22% for PBDB-T/ITIC based devices (2 wt% Bi2O2Se).
  • PCE increased from 14.59% to 16.28% for PM6/Y6 based devices (2 wt% Bi2O2Se), with enhanced air stability.

Conclusions:

  • 2D Bi2O2Se nanoflakes effectively enhance charge transport and morphology in PSCs.
  • The addition of Bi2O2Se leads to significant improvements in PCE and air stability.
  • Bi2O2Se is a promising material for advancing photovoltaic device performance.
