All-printable electronic devices: Towards high volume manufacturing methods

In the last five years rapid progress has been achieved in the field of printed electronics. For example the first all-printed transistors (OFET)s, solar cells, RFIDs and light emitting diodes (OLED)s were demonstrated in laboratory scale. In future printed electronics or “organic electronics” may integrate electronics devices and consumer goods innovatively and on low cost. Organic electronics and/or optoelectronics applications are already proposed in flexible packaging applications. On the other hand, printed devices are still in the stage where efficiencies are lower than using conventional microelectronic devices. This is mainly due to lack of suitable printing materials and unoptimized printing processes.
