Recent advances in hierarchical three-dimensional titanium dioxide nanotree arrays for high-performance solar cells
Hierarchical metal oxide nanotree array architectures with tunable three-dimensional (3D) morphologies and homo-/heterogeneous junctions, consisting of 1D/2D nanobranches grown epitaxially on the sidewalls of vertical 1D nanostructured trunks (resembling a tree), have been widely explored to demonst...

Zusammenfassung: | Hierarchical metal oxide nanotree array architectures with tunable three-dimensional (3D) morphologies and homo-/heterogeneous junctions, consisting of 1D/2D nanobranches grown epitaxially on the sidewalls of vertical 1D nanostructured trunks (resembling a tree), have been widely explored to demonstrate their huge potential in the development of high-performance photovoltaic devices. In this review, the growth of a wide variety of TiO
