Polymer Classification: Crystallinity01:21

Polymer Classification: Crystallinity

Unlike ionic or small covalent molecules, polymers do not form crystalline solids due to the diffusion limitations of their long-chain structures. However, polymers contain microscopic crystalline domains separated by amorphous domains.
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...

Area of Science:

  • Materials Science
  • Organic Electronics
  • Photovoltaics

Background:

  • All polymer organic solar cells (APSCs) offer mechanical robustness but lag behind small molecule devices in power conversion efficiency (PCE).
  • Achieving ideal morphology via precise chemical structure modulation of polymer acceptors (PAs) is a key challenge.
  • Optimizing PA conformation and molecular stacking is crucial for enhancing device performance.

Purpose of the Study:

  • To design and synthesize novel biaxial conjugate extension polymer acceptors (PAs) with tailored side chain/terminal substituents.
  • To control intermolecular non-covalent interactions, aggregation behavior, and microstructural orientation of polymer assemblies.
  • To enhance the power conversion efficiency (PCE) and operational stability of all polymer organic solar cells (APSCs).

Main Methods:

  • Designed two biaxial conjugate extension PAs with varied substituents.
  • Investigated the impact of substituents on intermolecular interactions and π-π stacking.
  • Fabricated ternary devices using the developed PAs and analyzed their photovoltaic performance and stability.

Main Results:

  • The alkoxy-functionalized PQxO-IT demonstrated stronger intermolecular interactions and tighter π-π stacking.
  • The PQx-FT:PQxO-IT composite improved charge carrier mobility and transport while reducing non-radiative decay.
  • A record PCE of 20.29% (certified 20.03%) was achieved for the ternary APSC device.
  • A flexible device achieved 18.93% PCE and excellent durability under continuous bending.

Conclusions:

  • Precise structure modulation of polymer acceptors is a viable strategy for high-performance organic photovoltaics.
  • The developed PAs offer a pathway to high-efficiency, mechanically robust, and durable flexible solar cells.
  • This work advances the field of all polymer organic solar cells towards practical applications.
