Abstract
A high efficiency dye-sensitized solar cell (DSC) with nanocrystallite TiO2 (nano- TiO2 ) secondary structure in the photoanode was successfully fabricated via a simple one step doctor blade printing method with a special nano- TiO2 paste containing micro-sized nano- TiO2 aggregates formed in situ. The special secondary structure in the photoanode shows improved optical absorption, increased light scattering ability, and enhanced electron transport and collection efficiency, resulting in high power conversion efficiency of 7.30% with 6 μm thin nano- TiO2 film in the photoanode, and the highest value of 9.28% by increasing the thickness of the nano- TiO2 film to 11 μm.
