Abstract
Homogeneous and dense arrays of nanowires are described. The nanowires can be formed in solution and can have average diameters of 40-300 nm and lengths of 1-3 μm. They can be formed on any suitable substrate. Photovoltaic devices are also described.

A method comprising:
- providing a substrate;
- depositing ZnO nanocrystals onto the substrate by dipping the substrate into a solution containing ZnO nanocrystals;
- and
- contacting the substrate with a solution formed from (Zn(NO3)2 6H2O) and methenamine (C6H12N4).
