Abstract

A bifunctional nanocrystal TiO2 structure able to offer both light scattering and electron generating properties was prepared by a simple method of adding a basic NH3·H2O agent to an acidic nanocrystal TiO2 paste to form bigger TiO2 nanocrystal aggregates. When used to prepare the second nanocrystal TiO2 layer in the photoelectrode, the photovoltaic performance of DSSCs were obviously enhanced, and the highest energy conversion efficiency attainable was 8.11%, which is much higher than that of a DSSC containing a single nanocrystal TiO2 layer prepared using the original acidic TiO2 paste (4.34%).
