Abstract
Transparent, conductive, and flexible Ag nanowire (NW)-polyimide (PI) composite films were fabricated by a facile solution method. Well-dispersed Ag NWs result in percolation networks on the PI supporting layer. A series of films with transmittance values of 53–80% and sheet resistances of 2.8–16.5 Ω/sq were investigated. To further verify the practicability of the Ag NWs-PI film in optoelectronic devices, we utilized it in a film heater and a flexible solar cell. The film heater was able to generate a temperature of 58 °C at a driving voltage of 3.5 V within 20 s, indicating its potential application in heating devices that require low power consumption and fast response. The flexible solar cell based on the composite film with a transmittance value of 71% presented a power conversion efficiency of 3.53%. These successful applications proved that the fabricated Ag NWs-PI composite film is a good candidate for application in flexible optoelectronic devices.
Highlights
Over the last several decades, conductive metal-oxide films represented by indium tin oxide (ITO)have been widely used as transparent electrodes in optoelectronic devices [1,2,3,4]
18 wt % PI in dimethylformamide solution was dropped onto the Ag NW film with the assistance of a glass rod to flatten the PI layer, and it was cured at 180 ◦ C for 30 min at a heating rate of 1 ◦ C/min
We demonstrated the fabrication of the Ag NW-PI composite film
Summary
Over the last several decades, conductive metal-oxide films represented by indium tin oxide (ITO). By controlling the optoelectronic properties of the composite film, various levels of heating performance could be achieved for the film heaters, and various current density-voltage characteristics could be obtained for the solar cells. These investigations confirm that the Ag NW-PI composite film is an excellent candidate for meeting diverse application requirements for flexible and transparent electrodes
