Ultra-thin transparent conducting oxides

AFM ImagesLimitations of ultra-thin transparent conducting oxides for integration into plasmonic-enhanced thin-film solar photovoltaic devices

Gwamuri, J., Vora, A., Khanal, R.R. et al. Mater Renew Sustain Energy (2015) 4: 12. doi:10.1007/s40243-015-0055-8

This study investigates ultra-thin transparent conducting oxides (TCO) of indium tin oxide (ITO), aluminum-doped zinc oxide (AZO) and zinc oxide (ZnO) to determine their viability as candidate materials for use in plasmonic-enhanced thin-film amorphous silicon solar photovoltaic (PV) devices.
