Inkjet-printing of indium tin oxide (ITO) films for transparent conducting electrodes

► Inkjet printing of ITO films. ► Ag-grid was inkjet-printed in between two ITO layers in order to improve the electrical property. ► Ag-grid inserted ITO films with 2 mm Ag-grid pitch showed the sheet resistance less than 3.4 Ω/sq and the transmittance higher than 82%.
