摘要: Abstract One of the most important challenges in field electrodeposition aqueous media concerns synthesis inorganic nanomaterials with excellent control film microstructure, morphology and crystallinity. In this work, we present a ground-breaking method for tailoring highly crystalline nanoporous layers ZnO upon transparent conductive oxide substrates which extends limit media. Being surfactant template-free, design well-defined nanostructure has been achieved by means an accurate electro-assisted generation hydrogen bubbles play role ‘gas template’ enabling formation dense to porous mesostructures depending on H2 evolution. Such were successfully introduced solid-state dye-sensitized solar cells. combination organic D-π-A dye (C220) CuSCN as hole transporter material, 2.1% power conversion efficiency.
