  • Conference paper (peer-reviewed)abstract
    • We present a current supply, comprising a single organic thin-film transistor (OTFT), for the charging of supercapacitors. The current supply takes power from the electric grid (115 V AC, US standard), converts the AC voltage to a quasi-constant DC current (similar to 0.1 mA) regardless of the impedance of the load, and charges the supercapacitor. Solution-processed OTFTs based on the popular polymeric semiconductor poly(3-hexylthiophene- 2,5-diyl) have been developed to rectify the 115 V AC voltage. A diodeconfigured OTFT was used as a half-wave rectifier. The single OTFT current supply was demonstrated to charge a 220 mF supercapacitor to 1 V directly using 115 V AC voltage as the input. This work paves the road towards all-printable supercapacitor energy-storage systems with integrated chargers, which enable direct charging from a power outlet.

  • The applications of OECTs in supercapacitor balancing circuits
  • 2016
  • In: 2016 7th International Conference on Computer Aided Design for Thin-Film Transistor Technologies (CAD-TFT). - : IEEE. - 9781509026876 ; , s. 23-23
  • Conference paper (peer-reviewed)abstract
    • In this paper, we investigate using OECTs in differential amplifiers and cell voltage equalizers for supercapacitor balancing circuits. The differential amplifier based on OECTs can sense voltage difference and the voltage equalizer consisting of a microcontroller and OECTs can be used to charge supercapacitors to desired voltages.
