Transparent conductive electrodes (TCEs) possessing a combination of high optical transmission and good electrical conductivity find applications in numerous optoelectronic devices. A low cost fabrication of a fine metal‐mesh structure on rigid (glass) and flexible (polyethylene terephthalate – PET) substrates as a promising and feasible approach for fulfilling large size TCE requirements is proposed. A roll‐to‐sheet ultraviolet imprinting protocol to transfer microtrench structures using a flexible Polydimethylsiloxane stamp is utilised. The conductive silver ink is filled into the microtrench structures by controlling the processing parameters which include pressure, scraping angle and speed. The metal‐mesh based glass and PET substrates show a transmission of about 90%, while the electrical resistance is as low as 6 Ω/□. Thus, this method can be utilised as an economically viable alternative to doped indium oxide in TCE applications.
