Vertically aligned ZnO nanorod arrays grown by Chemical Bath Deposition on bare- and ITO-coated glass substrates

Thin films comprising vertical aligned ZnO nanorod arrays are currently used for sensing and photovoltaic applications. Chemical Bath Deposition (CBD) is a low-cost technique for the semiconductor thin films deposition. This work reports the CBD growth of ZnO nanorods (NRs) on different substrates for potential application in thin film solar cells. It was found that, the successful deposition of thin films composed of vertical aligned ZnO nanorods on bare and ITO-coated glass substrates strongly depends on the seed layer characteristics.
