Printed Electronics Award Winners Announced at Printed Electronics Europe

PBTTT outperforms the current state-of-the-art polymeric semiconductor. The well-known and characterized poly 3-hexylthiophene (P3HT), available in different qualities from several suppliers including Merck, is the most widely adopted organic semiconductor. The new material not only offers charge mobilities an order of magnitude higher than P3HT but also exhibits significant stability improvements during processing and device operation. This higher performance eases the equipment requirements and encapsulation schemes, widens the process window, allows less restrictive device designs, and most importantly, allows access to applications not previously achievable with polymeric systems. Charge mobilities equivalent to amorphous silicon, the semiconductor used in flat panel TFTs, can now be demonstrated with printable semiconducting polymers.
