Rolith has received an exclusive licence to methods of micro and nano-patterning substrates to make transparent conductive electrodes from the University of Michigan Office of Technology Transfer (U-M Tech Transfer). The licensed process, developed by University of Michigan professor Jay Guo, is based on patterning that uses continuous optical lithography. According to him, it also offers a low cost, high throughput approach to manufacturing transparent conductive electrodes.

Transparent conductive electrodes are critical to the operation of various optoelectronic devices and are commonly used in high volume applications such as displays, solar cells, "smart" windows and LEDs. Transparent conductive metal oxides such as indium tin oxide (ITO) are used for this purpose. However, there is a growing need to replace ITOs with alternative solutions for reasons of cost, availability and performance.

Recent discoveries regarding the optical properties of nanopatterned metals have opened up an important opportunity to develop a new class of transparent electrodes without relying on ITOs. The nanostructured electrodes technology licensed from U-M Tech Transfer in combination with the existing "Rolling Mask Lithography" capabilities at Rolith offer a convenient and cost effective manufacturing solution to the market, the organisations added.
