Unlike most computer chips, which use transistors made of silicon, the NIST spray-on computer chip utilises an organic semiconductor, called poly(3-hexylthiophene), or P3HT. By spraying the P3HT over a deposited circuit architecture of gold and silicon, the NIST team can lay down vast swaths of electronics quickly and cheaply.
The NIST scientists admit that translating this breakthrough into a concrete new technology will prove challenging. However, once the technique is perfected, it can result in very significant price drops for both solar panels and large display screens.
