Development of Y2O3: Ho3+/Yb3+ Upconverting Nanophosphors for Enhancing Solar Cell Efficiency of Dye-Sensitized Solar Cells

Light scattering behavior of dye-sensitized solar cells (DSSCs) containing Y2O3: Ho3+ /Yb3+ upconverting (UC) nanophosphor has been studied. To study the influence of UC nanophosphors on photovoltaic performance of DSSCs, UC nanophosphors have been introduced into the TiO2 film to form the hybrid film. The electron ejection ability, current density (JSC ), open-circuit voltage (VOC ), and power co...
