Microstructure Properties of ZnO/ Indium Tin Oxide and ZnO/CuInSe2 grown by Electrochemical Deposition
OPEN ACCESS
In this research, we grew a ZnO film as a buffer layer on indium tin oxide (ITO) substrates and CuInSe2/ITO (CIS/ITO) substrates by electrochemical deposition. To examine material quality of ZnO films, multiple material and optical analyses including scanning electron microscope images, electron probe microanalyzer images, UV-VIS, and x-ray diffraction were conducted. The results indicate that an appropriate amount of H2O2 might enhance the growth of ZnO films on the ITO substrate. Furthermore, triethanolamine addition might suppress the reaction between KCl and the CIS substrate to enhance the growth of the ZnO film on the CIS substrate. The ZnO/CIS structure may replace the toxic CdS/CIS structure for the further development for the CIS solar cell.
