We present the design and realization of silver grid transparent electrodes (SGTEs) easily fabricated byfemtosecond laser direct writing of silver aqueous solution. The fabricated SGTEs with a sheetresistance down to 47 Ω/□ and optical transmittance up to 93% are demonstrated. These sheetresistance and transmittance values are comparable to commercially available indium tin oxide. High uniform morphology of the directly written SGTEs results in the ultra-stable tailored performance parameter at electronic and optical fields. The sheet resistance and transmittance can be tailored precisely by manipulating the filling fraction of the uniform SGTEs. This study provides an approach for creating SGTEs in a controllable fashion, and the SGTEs exhibit high transmittance and low sheetresistance, which could open up new avenues towards widespread application in electronics, photovoltaics, and optoelectronics.
