Description
Summary:In this work, Pt-TiO2-coated FTO glass substrate has been synthesized by the thermal decomposition method toward the efficient reduction of triiodide ions, and excellent transmittance for rear-side efficiency of the third-generation solar cells. As the results, a lower charge-transfer resistance and higher transmittance of TiO2-Pt electrode were obtained compared to the Pt electrode. Therefore, the cell fabricated with Pt-TiO2 electrode did not only show a high front-efficiency but also provides an excellent rear-efficiency, that lead to its higher power conversion efficiency compared to that of a cell fabricated with Pt electrode. Furthermore, the cell fabricated with TiO2-Pt electrode also shows an ultra-stability which indicated long-term stability of TiO2-Pt electrode under the reduction of triiodide ions. The finding in this work provides the approaches in the development of bifacial liquid-junction photovoltaic devices. [Display omitted]
