Densely packed ZnOnanocolumns (NCs), perpendicularly oriented to the fused-silica substrates were directly grown under hydrothermal conditions at 90 °C, with a growth rate of around 0.2 μm/h. The morphology of the nanostructures was visualized and analyzed by scanning electron microscopy (SEM). The
development of thin film solar cells based on ZnO NCs.

The widely accepted design of thin-film silicon (TF
advantageously used for all other thin-film solar cells.
So far, a wide diversity of methods have been used for the preparation of ZnOnanocolumns such as metal organic chemical vapor deposition (MOCVD) [11], electrochemical deposition [12], sputtering [13], reactive ion etching [5] and the hydrothermal method
