Non-ITO transparent electrode  

@Home Ë Technology Ë Non-ITO transparent electrode

Although ITO (Indium Tin Oxide) is the most common transparent electrode, it is well known that ITO contains issues in cost because Indium is a rare metal and the fabrication processes of ITO layer on substrates are expensive due to the vacuum and photolithography processes.    Based on such background, various non-ITO transparent electrode technologies have been developed.

We have developed several novel non-ITO transparent electrode technologies shown below.

 

Ÿ Non-ITO Transparent Electrode with Implanted Metal-mesh Structure (2020)

 

The conducting polymers for an anode of OLED devise were developed.  OLED devices with the developed conducting polymer show comparable performance with the reference OLED devices with normal ITO.  ITO-free OLED devices were developed using the developed conducting polymer and an assisting bass line [1].

Ÿ Stacking electrode consisting of silver nanowire and conducting polymer

The stacking electrode consisting of silver nanowire and conducting polymer was developed.

Flexible OLED devices on ultra-thin glass were developed using the stacking electrode consisting of silver nanowire and conducting polymer.

 

Ÿ Coducting polymer
