Abstract
Silver nanowire is one of the most promising substitute material for indium tin oxide. However, electrode made of silver nanowires network has poor long term air stability and current operation stability, which hinder its practical application. In this thesis, to solve these problems a AgNWs-HZO composite electrode was developed by depositing ALD Hafnium-doped zinc oxide on silver nanowires film. The composite electrode showed 87.2% total transmittance at 550 nm and 26.3 Ω/□ in sheet resistance, which are comparable to commercial ITO. In addition, after 9-days storage in 85°C/85% relative humidity environment, the resistance of composite electrode was raised less than 1.2 times and after 120-hrs current operation test at 88 mA/cm2, the output voltage of composite electrode was raised only 1.13 times. Moreover, the perovskite solar cells on AgNW-HZO composite electrode showed good photovoltaic performance as much as solar cells on commercial ITO. Hence our composite electrode not only improves air stability and current operation stability of silver nanowires but also has potential to serve as transparent electrode in optoelectronic application.
