摘要：
Gold nanoparticles of various sizes have been prepared and deposited on top of the TiO2 film in dye-sensitized solar cells (DSSCs) in order to enhance the light harvesting efficiency. The light scattering effect gradually strengthens as the size of Au nanoparticles increases from 48 to 203 nm. It is impressive that 1 mu g cm(-2) deposition of 203 nm gold nanoparticles on top of the TiO2 film enhances the light scattering efficiency remarkably, increasing the short-circuit photocurrent from 14.37 mA cm(-2) to 17.81 mA cm(-2) by 24% and the power conversion efficiency from 7.44% to 10.03% by 35%.
