Recrystallization: Solid–Solution Equilibria

1.0K
Recrystallization is a purification technique used to separate impurities from solid compounds. In this technique, no chemical reactions occur. Instead, it exploits physical properties only, specifically, the solubility differences between the desired compound and impurities, either at a single temperature or at different temperatures, and under other selected conditions. The solid-solution equilibrium (solubility equilibrium) of each component in the solution represents a binary phase...

Crystal Growth: Principles of Crystallization

1.5K
Crystallization is a phase transformation process in which crystals are precipitated from a supersaturated solution or formed from other sources. During crystallization, atoms or molecules arrange themselves into a well-defined, rigid crystal lattice to minimize energy.
Initiating crystallization involves manipulating the concentration of the solute and the temperature of the solution. Since crystal growth occurs when the ratio of concentration and solubility of the solute in the solvent...

Polymer Classification: Crystallinity

2.7K
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...

Ziegler–Natta Chain-Growth Polymerization: Overview

3.2K
Ziegler–Natta polymerization is another form of addition or chain‐growth polymerization used for synthesizing linear polymers over branched polymers. The catalyst used for polymerization is the Ziegler–Natta catalyst, named after Karl Ziegler and Giulio Natta, who developed it in 1953. This catalyst is an organometallic complex of titanium tetrachloride and triethyl aluminum, with the active form of the catalyst being an alkyl titanium compound. Using the Ziegler–Natta...

  • Materials Science
  • Organic Electronics
  • Photovoltaics

Background:

  • Controllable active layer morphology is crucial for enhancing organic solar cell (OSC) performance.
  • Existing strategies often struggle with precise control over morphology evolution.

Purpose of the Study:

  • To employ a quaternary strategy for precise modulation of crystallization kinetics and active layer morphology in OSCs.
  • To investigate the synergistic effects of polymer donor D18-Cl and small molecule acceptor AITC on morphology.
  • To achieve optimized 3D morphology for improved device performance and reduced energy loss.

Main Methods:

  • Incorporation of polymer donor D18-Cl and small molecule acceptor AITC into a host D18:N3 system.
  • In situ spectroscopic measurements during film formation to monitor crystallization kinetics and morphology evolution.
  • Analysis of the effects of dual-guests on donor/acceptor aggregation and intermixing.

Main Results:

  • D18-Cl acted as a nucleator, promoting D18 aggregation and donor/acceptor intermixing.
  • AITC acted as a plasticizer, opposing N3 aggregation and intermixing kinetics.
  • The combined effect resulted in synergistic control over fibrillar networks, multi-length scale morphology, and vertical phase distribution, leading to an optimized 3D morphology.

Conclusions:

  • The quaternary strategy enables synergistic control over active layer morphology through mutually compensational effects of dual-guests.
  • Optimized morphology enhances exciton dissociation, charge transfer, suppresses recombination, and reduces energy loss.
  • Achieved a power conversion efficiency of 20.1% for single-junction OSCs, demonstrating an effective approach for high-performance devices.
