Open structure ZnO/CdSe core/shell nanoneedle arrays for solar cells

Open structure ZnO/CdSe core/shell nanoneedle arrays were prepared on a conducting glass (SnO(2):F) substrate by solution deposition and electrochemical techniques. A uniform CdSe shell layer with a grain size of approximately several tens of nanometers was formed on the surface of ZnO nanoneedle co...

description Open structure ZnO/CdSe core/shell nanoneedle arrays were prepared on a conducting glass (SnO(2):F) substrate by solution deposition and electrochemical techniques. A uniform CdSe shell layer with a grain size of approximately several tens of nanometers was formed on the surface of ZnO nanoneedle cores after annealing at 400°C for 1.5 h. Fabricated solar cells based on these nanostructures exhibited a high short-circuit current density of about 10.5 mA/cm(2) and an overall power conversion efficiency of 1.07% with solar illumination of 100 mW/cm(2). Incident photo-to-current conversion efficiencies higher than 75% were also obtained.
