In the preparation process, TiO2 and phosphor particles were mixed to make photoelectrodes with bilayer (TiO2/mix), 3-layer (TiO2/mix/TiO2) and 4-layer (TiO2/mix/TiO2/mix) structures. The cell with the bilayer structure (TiO2/mix) after treating with TiCl4 solution showed the highest light-to-electric energy conversion efficiency (8.78%), which was ∼25.8% higher than that of a cell with a pure TiO2 layer under the same experimental conditions. The improvement in the energy conversion efficiency of DSSCs was attributed to phosphor enhanced incident light-harvesting via up- and down-conversion luminescence processes, resulting in an increase in the photocurrent. date: 2015 date_type: published official_url: DOI: 10.1039/C5TA02363G full_text_status: none publication: J.
