摘要：

Hierarchical Zn2SnO4 nanosheets consisting of nanoparticles are synthesized for the first time through the facile hydrothermal process in the presence of F. Dye-sensitized solar cell based on hierarchical Zn2SnO4 nanosheets photoelectrode shows a remarkable enhancement in power conversion efficiency (4.82%) compared to that of nanoparticles (4.01%) because of its superior light scattering ability, faster electron transport rate and slower charge recombination rate, which were confirmed by the UV-vis diffuse reflectance spectroscopy, intensity-modulated photocurrent/photovoltage spectroscopy and electrochemical impedance spectroscopy. Further TiCl4 treatment of Zn2SnO4 nanosheets photoelectrode results in an impressive photovoltaic performance of 5.44%. (C) 2013 Elsevier Ltd. All rights reserved.
