Given the strong dependency of these devices’ performance on their geometrical dimensions and considering the increasing need for larger scale and low cost fabrication, research on novel processing methods is paramount. Here, we review the most common processing techniques used for OECT fabrication, starting from classic methods such as spin coating and electropolymerization to more recent and complex ones like orthogonal lithography and 3D printing.
