Application of Nano-SiO₂ on Photoanode of Quantum Dots Sensitized Solar Cells

Abstract:

A new TiO₂-nanoSiO₂ hybrid film is prepared through adding the nanosized SiO₂ into the TiO₂. A more environmental and simpler method is found to prepare CdSe quantum dots (QDs) sensitized TiO₂nanoSiO₂ hybrid films for the quantum dots-sensitized solar cells (QDSSCs) application. The prepared colloidal CdSe QDs (~2.6nm) was linked to the TiO₂-nanoSiO₂ hybrid film using 3-mercaptopropionic acid (3-MPA) as a linker molecule slowly with drop and drop. The power conversion efficiency of 1.33% was achieved using the sensitization photo-electrode prepared by using TiO₂nanoSiO₂ hybrid film modified with CdSe (TiO₂-nanoSiO₂/CdSe) under the illumination of one sun.
