Enhancing Light Harvesting by Hierarchical Functionally Graded Transparent Conducting Al-doped ZnO Nano- and Mesoarchitectures
摘要:
提出了一种功能梯度掺铝氧化锌结构,它结合了导电性,可见光透明性和光散射与机械柔性。纳米和介观结构,由一个层次,大表面积,中孔树状结构演变成一个紧凑的层,在室温下合成,是完全兼容的塑料基板。光捕获能力是通过显示作为有源层的低带隙聚合物的光吸收的高达100%的改善来证明的。
英文摘要:
A functionally graded Al-doped ZnO structure is presented which combines conductivity, visible transparency and light scattering with mechanical flexibility. The nano and meso-architecture, constituted by a hierarchical, large surface area, mesoporous tree-like structure evolving in a compact layer, is synthesized at room temperature and is fully compatible with plastic substrates. Light trapping capability is demonstrated by showing up to 100% improvement of light absorption of a low bandgap polymer employed as the active layer.
