Piezoelectric dispenser printing and intense pulse light sintering of AgNW/PEDOT:PSS hybrid transparent conductive films

Abstract A hybrid transparent conductive films (TCFs) combining silver nanowires (AgNWs) and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) was fabricated using a piezoelectric dispenser printing method. The innovation lies in optimizing the ink composition and employing intense pulsed light sintering to enhance the TCF’s performance. The optimized AgNW/PEDOT:PSS mixture, with an 8:2 ratio, achieved a figure of merit (FOM) of 28.05 × 10 −3 Ω −1 , corresponding to a sheet resistance of 9.93 Ω sq −1 and a transmittance of 88.0%. This represents a significant improvement over the pre-sintering FOM of 24.09 × 10 −3 Ω −1 . Additionally, the hybrid TCFs exhibited outstanding structural stability, maintaining functionality after 7000 mechanical bending cycles. The results enable applications in flexible optoelectronic devices, and highlight the potential of this method to produce high-performance, flexible, and durable transparent electrodes, advancing the development of next-generation optoelectronic devices.
