a Sheet resistance of Ag NWs films vs the spin-coating speed at different concentration of Ag NWs. b Comparison of optoelectronic performance of Ag NTEs fabricated by different volume of Ag NWs solutions. The concentration of Ag NWs solution is 6 mg/mL, and the volume of each spin coating is 25 μL. The inset is the FOM values of Ag NWs films vs the volume of Ag NWs solution. c–f SEM images of Ag NWs films fabricated by different volumes of Ag NWs solutions, c 25 μL, d 50 μL, e 75 μL, f 100 μL, respectively. All the scale bars are 5 μm
