| Outline of Final Research Achievements |
We developed a novel method to fabricate textured surfaces on transparent conductive SnO 2 films by processing substrates through a bottom-up technique with potential for industrially scalable production. The substrate processing consists of three steps: deposition of precursor Sn films on glass substrates, formation of a self-assembled Sn nanosphere layer with reductive annealing, and conversion of Sn to SnO 2 by oxidative annealing. Ta-doped SnO 2 films conformally deposited on the self-assembled nanospherical SnO 2 templates exhibited attractive optical and electrical properties, namely, enhanced haze values and low sheet resistances, for applications as transparent electrodes in photovoltaics.
