Description

PTAA – SOL2426

CAS: 1333317-99-9

Excellent semiconductor material that transports holes and blocks electrons due to its electron-rich components.

Key Properties of PTAA

  • High charge mobility → Improves the efficiency of hole transport in optoelectronic devices.
  • Excellent thermal and environmental stability → Ideal for demanding applications in solar cells and LEDs.
  • Wide bandgap (~3.0 eV) → Facilitates the use as a hole transport medium with minimal absorption in the visible spectrum.
  • Good solubility in organic solvents → Allows solution processing, reducing manufacturing costs.
  • Compatibility with perovskite layers → Widely used in high-performance perovskite solar cells.

Main Applications

  1. Perovskite solar cells:
    serve as a hole transport layer (HTL), enhancing charge extraction and bolstering the stability of the device.
  2. Organic light-emitting diodes (OLEDs):
    support efficient charge injection and movement in advanced light-emitting systems.
  3. Photodetectors and optical sensors:
    benefit from its robust stability and efficiency, making it suitable for light detection and adaptable electronic uses.
  4. Organic field-effect transistors (OFETs):
    exhibit high charge mobility, positioning them as a superior option for flexible, low-power electronic applications.
