Abstract Al-doped ZnO (AZO) is pursued as an alternative low-cost transparent conductive oxide (TCO) to expensive ITO. Atomic layer deposition grown AZO films showing resistivity of 5 × 10−3 Ωcm and transmittance >85% in the visible region are reported. Au-assisted GaAs nanowires are grown directly on an optimized AZO coated glass and a GaAs nanowire-polymer hybrid device on glass is demonstrated which confirms that the as-grown GaAs nanowires form a perfect ohmic contact to AZO film. The device shows that AZO can be used as transparent electrode as well as low-cost growth platform for GaAs NWs. Finally, a simple device idea is proposed to fabricate optically transparent GaAs nanowire based solar cells on low-cost glass.

玻璃上的混合 GaAs 纳米线聚合物器件：Al 掺杂的 ZnO (AZO) 作为基于纳米线的光伏应用的透明导电氧化物

摘要 掺杂铝的 ZnO (AZO) 被用作替代昂贵的 ITO 的低成本透明导电氧化物 (TCO)。据报道，原子层沉积生长的 AZO 薄膜电阻率为 5 × 10−3 Ωcm，在可见光区的透射率 > 85%。Au 辅助的 GaAs 纳米线直接生长在优化的 AZO 涂层玻璃上，并展示了玻璃上的 GaAs 纳米线-聚合物混合器件，这证实了生长的 GaAs 纳米线与 AZO 膜形成完美的欧姆接触。该装置表明 AZO 可用作透明电极以及 GaAs NW 的低成本生长平台。最后，提出了一种在低成本玻璃上制造基于光学透明 GaAs 纳米线的太阳能电池的简单装置想法。
