Organic rectifier diodes operating at 10 MHz made using roll-to-roll compatible mass printing processes to define patterns and deposit inks are reported. The diodes consist of a layer of poly(triarylamine) sandwiched between layers of silver and copper. No high resolution prepatterning of any surfaces was performed, thus the entire process could be carried out on large-scale roll-to-roll production lines. The organic diode based rectifier circuit generates a DC output voltage of approximately 2.7 V at 10 MHz, using an input signal with zero-to-peak voltage amplitude of 10 V. The result demonstrates the possibility of printed organic diodes for RFID applications.
