Flexible Polymer Rectifying Diode on Plastic Foils with MoO3 Hole Injection
2022 IEEE International Conference on Flexible and Printable Sensors and Systems (FLEPS)(2022)
Abstract
In this work, a flexible solution processed polymer diode with a structure of aluminum/indacenodithiophene-benzothiadiazole (C
16
-IDT-BT)/molybdenum trioxide/gold was developed. A DC rectification ratio of 7×10
3
was achieved at 2 V with a forward current density of 2.6 mA/cm
2
and a reverse current density of 0.37 µA/cm
2
. The UV-ozone treated MoO
3
layer acted as a hole injection layer for the C
16
-IDT-BT layer to enhance the forward current density. The Au electrode with a higher work function compared to Ag was a superior anode for the polymer diode. The diode can be used as a blocking diode to allow the current to flow in the desired direction.
