Organic power electronics achieves mains rectification

Organic power electronics achieves mains rectification

This is believed to be the first time organic devices have achieved such voltages and marks the beginning of organic power electronics and the possibility of creating flexible and ecologically benign power conversion circuits.

The team is drawn from researchers at Linkoping and Umea universities in Sweden. The semiconductor material is poly(3-hexylthiophene-2,5-diyl) and a diode-configured device was used a half-wave rectifier and used to rectify 115V AC voltage, the US mains standard. Until now this has not been possible, because of the tendancy for high voltages to breakdown the organic electronics.

Docent Deyu Tu from Linkoping University led a project where they were able to drive organic light-emitting devices and charge supercapacitors using electricity from an ordinary wall socket. The diode-connected organic thin-film transistors operated at high voltages up to 325V.

The results have been published in two journals – Organic Electronics and ECS Transactions
