OP6161 Spiro-TTB (CAS No. 515834-67-0)

Spiro-TTB Description

Spiro-TTB is an organic semiconductor material primarily used as a hole transport material (HTM) in optoelectronic devices, including perovskite solar cells and organic light-emitting diodes (OLEDs). It is a derivative of spirobifluorene with enhanced properties making it suitable for charge transport in thin film devices.

Spiro-TTB Specifications

Spiro-TTB Applications

• Perovskite Solar Cells: Spiro-TTB is used as a hole transport material (HTM) in perovskite solar cells, facilitating the movement of positive charge carriers (holes) from the perovskite layer to the electrode. Its energy level alignment with the perovskite material enhances charge extraction and the overall efficiency of the device.
• Organic Light-Emitting Diodes (OLEDs): In OLEDs, Spiro-TTB serves as a hole transport layer (HTL) to enable efficient charge injection from the anode into the emitting layer, resulting in improved device performance and light emission.
• Organic Photovoltaics (OPVs): Spiro-TTB can also be utilised in organic photovoltaic devices to enhance charge transport and efficiency.

Frequently Asked Questions

Q1: What is Spiro-TTB?

Answer: Spiro-TTB is an organic semiconductor used as a hole transport material (HTM) in optoelectronic devices such as perovskite solar cells, organic light-emitting diodes (OLEDs), and organic photovoltaics (OPVs). It assists in the transport of positive charge carriers (holes) within the device, thereby contributing to its efficiency.

Q2: How does Spiro-TTB improve the performance of perovskite solar cells?

Answer: Spiro-TTB enhances performance through efficient transport of positive charge carriers (holes) from the perovskite layer to the electrode. Its energy level alignment reduces recombination losses and increases the overall efficiency of the solar cell.

Q3: How is Spiro-TTB typically processed in device manufacturing?

Answer: Spiro-TTB is usually dissolved in organic solvents (e.g., chlorobenzene or toluene) and applied via spin-coating or solution processing. Once a uniform film is formed, it acts as a hole transport layer in devices such as solar cells and OLEDs, supporting charge transport.
