Paintable Electronics

April 1, 2010

An organic semiconductor — poly(3-hexylthiophene), or P3HT — may be a future viable candidate for creating large-area electronics, such as solar cells and displays that can be sprayed onto a surface as easily as paint, a research team at the National Institute of Standards and Technology (NIST) has found.

This airbrush technique deposits a material called P3HT to create spray-on transistors, which perform comparably to lab-standard equivalents made by spin coating (NIST)


The material could overcome one of the main cost hurdles blocking the large-scale manufacture of organic thin-film transistors, and could lead to a host of devices inexpensive enough to be disposable. It would also require less power and do things silicon devices cannot: bend and fold, for example.
