The dye sensitized solar cell(DSSC), which converts solar light into electric energy, is expected to be a promising renewable energy source for today’s world. In this work, dye sensitized solar cells, one containing a single layer and one containing a double layer, were fabricated. In the double layer DSSC structure, the under-layer was TiO_2-P25 film, and the top layer consisted of a mixture of TiO_2-P25 and TiO_2 nanotubes. The results indicated that the efficiency of the DSSC with the double layer structure was a significant improvement in comparison to the DSSC consisting of only a single film layer. The addition of TiO_2-P25 in the top layer caused an improvement in the adsorption of dye molecules on the film rather than on the TiO_2 nanotubes only. The presence of the TiO_2 nanotubes together with TiO_2-P25 in the top layer revealed the enhancement in harvesting the incident light and an improvement of electron transport through the film.
