摘要：

Dye-sensitized solar cells (DSSCs) based on ZnO nanostructures have been fabricated by spray deposition of hydrothermally synthesized ZnO nanoparticles and using vertical ZnO nanorod arrays prepared in a continuous spray pyrolysis reactor. The self-assembled nanostructures, due to the presence of the electric field during spray deposition, improve the cell efficiency (eta) from similar to 2.8% for ZnO nanocrystalline film (thickness similar to 4.3 mu m) to 4.7% for ZnO nanostructured film (enhancement of similar to 60%). The best performance with ZnO nanorods cell structure gives eta of 1.70 for the layer thickness and cell area of similar to 2 mu m & 0.25cm(2), respectively. (C) 2011 Published by Elsevier B. V.
