摘要：
Inkjet printable and highly conductive PEDOT: PSS films on hydrophobic silicon surface were successfully developed in this work. Contact angle measurements were used to validate the substrate surface treatments for enhanced ink wetting characteristics. The improved wettability of the Si surface promotes easy spreading of the PEDOT:PSS solution, allowing a uniform coverage of the surfaces. Several inkjet printing parameters, including droplet spacing, substrate temperature and number of layers, were explored to study the impact they have on the film thickness and roughness. With an optimized printing setting, the number of surface defects and shunting problems in PEDOT:PSS films were drastically reduced. Lastly, the inkjet printed PEDOT:PSS thin film was implemented into a solar cell structure and proven to be an effective hole transport layer.
