PEDOT-TMA - Application Overview

Application Overview

Several devices and materials have been described in both journals and the patent literature that use PEDOT-TMA as a critical component. In this section, a brief overview of these inventions is given.

• Patternable OLED's: In a study by researchers at General Electric, PEDOT-TMA was used in the hole injection layer in a series of OLED devices. They have also filed a patent application to protect this invention.

• Ion Selective Membranes: PEDOT-TMA was used as a key ingredient in ion selective membranes

• Dye Sensitized Solar Cell: PEDOT-TMA was used in the construction of effective Dye-sensitized solar cells. The PEDOT-TMA was spun-coat to give a 15 nm thick layer which was used as the counter-electrode in a series of Dye-sensitized solar cells. Efficiencies as high as 7.85% were obtained.

• Flexible Touch Screens: PEDOT-TMA was used in the construction of electrodes for flexible touch screens as described in a patent application by the Honeywell Corporation.

• Energy Storage and Conversion Devices: Synkera Technologies, Inc. filed a patent application detailing a variety of energy storage and conversion devices that use PEDOT-TMA in their construction.

• Glucose Sensor: A glucose sensor was prepared by Gymama Slaughter of Virginia State University.

• Carbon Nanotube Composites: Researchers from Los Alamos National Laboratory used PEDOT-TMA to prepare composites with carbon nanotubes. These composites form highly aligned arrays of the nanotubes, and exhibit high conductivity at room temperature (25.0 S/cm).

• Metal Wire-Based Photovoltaic Device: Researchers from The Institute of Advanced Energy at Kyoto University used PEDOT-TMA to fabricate organic photovoltaic devices.
