Invisible Ag mesh transparent electrodes (TEs), with a width of 7 mu m, were prepared on a curved glass surface by electrohydrodynamic (EHD) jet printing. With a 100 mu m pitch, the EHD jet printed the Ag mesh on the convex glass which had a sheet resistance of 1.49 Omega/square. The printing speed was 30 cm s(-1) using Ag ink, which had a 10 000 cPs viscosity and a 70 wt% Ag nanoparticle concentration. We further showed the performance of a 3-D transparent heater using the Ag mesh transparent electrode. The EHD jet printed an invisible Ag grid transparent electrode with good electrical and optical properties with promising applications on printed optoelectronic devices.
