Low Temperature Fabrication of Transparent Conductive Electrode With High Ultraviolet Transmittance Down to Wavelength of 250 nm

Abstract

Indium tin oxide (ITO) is a broadly deployed transparent conductive electrode (TCE) with various applications in solar energy harvesting and optoelectronics. However, the low transmittance of ITO in the ultraviolet range has motivated researchers to opt for alternative materials as TCE. In this paper, the fabrication of a hybrid TCE made up of silver nanowire (AgNW) and peroxo‐constructed amorphous strontium stannate (pcaSS) is reported, employing facile spin coating solution‐processed method at 150 °C. The fabricated TCE demonstrated low sheet resistance of 32.8 Ω sq−1 and high transmittance of 88.2% at 550 nm. Furthermore, benefitting from the ultra‐high band gap of as‐synthesized pcaSS (4.5 eV), this TCE maintained its high transmittance (above 80%) inside ultraviolet range down to wavelength of 250 nm. This research contributes to the fabrication of more efficient solar energy and ultraviolet optoelectronic devices.
