Zinc oxide film and nanowires were grown on glass and Si substrates for solar cell by metal organic chemical vapor deposition (MOCVD) without any catalyst. The MOCVD was carried out in the temperature ranging from 400oC to 800oC and substrate temperature resulted in changing - the growth mode from film to nanowires. The solar cell was successfully fabricated using these grown ZnO nanowires, which mainly act as a light collection layer enhancing transmittance, but reflection such as anti-reflection coating.
