Transparent conducting electrodes have many potential applications, such as in organic light-emitting diodes.

Light-emitting diodes offer the promise of efficient light generation for both specialty lighting and for general illumination.  They are, however, essentially just like computer chips, and they require the same kind of high-value fabrication equipment and processes.  Organic LEDs have the same kind of promise, but they also may be much easier to manufacture—eventually.  For now, a lot of work remains to be done, such as creating transparent conductive films.  A research team led by George Washington University in Washington, DC developed an aluminum-doped zinc film that may help.  To ensure proper deposition, the substrates were first cleaned in an ultrasonic cleaner.
