Enhancement of ZnO Dye-Sensitized Solar Cell Performance by Modifying Photoelectrode Using Two-Steps Coating-Etching Process

Enhancement of ZnO Dye-Sensitized Solar Cell Performance by Modifying Photoelectrode Using Two-Steps Coating-Etching Process

© 2015 The Authors. Published by Elsevier Ltd. ZnO photoelectrodes modified by two-steps coating-etching process with chemical wet etchants for dye-sensitized solar cell were investigated. The ZnO films were coated on a fluorine-doped tin oxide glass substrate and etched by mixed acid solution of HC...
