Area of Science:

  • Materials Science
  • Organic Electronics
  • Photovoltaics

Background:

  • Donor-acceptor alternating polymers are crucial for organic photovoltaics (OPVs).
  • The impact of atom substitution on polymer properties is an active research area.

Purpose of the Study:

  • To develop and evaluate novel benzodithiophene (BDT)/naphthodifuran (NDF) and benzoselenadiazole (BSe)/benzothiadiazole (BT) polymers for OPVs.
  • To investigate the effect of selenium (Se) versus sulfur (S) substitution in the acceptor unit on polymer optoelectronic properties and device performance.

Main Methods:

  • Synthesis of four isostructural donor-acceptor alternating polymers.
  • Characterization of optoelectronic properties including absorption spectra and energy levels (HOMO).
  • Fabrication and testing of bulk-heterojunction solar cells using polymer:fullerene blends.
  • Theoretical calculations to support experimental findings.

Main Results:

  • Selenium-containing polymers (BDT-BSe) showed extended absorption, narrowed bandgaps, and higher HOMO energy levels compared to sulfur analogs (BDT-BT).
  • Theoretical calculations corroborated the experimental observations on energy level modulation.
  • The BDT-BSe copolymer achieved a peak power conversion efficiency (PCE) of 5.40% in bulk-heterojunction solar cells when blended with PC71BM (1:2, w/w).
  • BSe-based polymers generally outperformed BT-based polymers in photovoltaic applications.

Conclusions:

  • One-atom substitution (Se for S) in the acceptor unit significantly impacts polymer optoelectronic properties and OPV performance.
  • Selenium incorporation leads to enhanced photovoltaic characteristics.
  • Device performance is sensitive to processing conditions and active layer morphology.
