英文摘要	Near infrared to visible up-conversion of light by rare earth ion-doped phosphors (NaYF₄:Yb³⁺, Er³⁺) that convert multiple photons of lower energy to higher energy photons offer new possibilities for improved performance of photovoltaic devices. Here, up-conversion phosphor NaYF₄:Yb³⁺, Er³⁺ doped nanocrystalline TiO₂ films are designed and used as a electrode for dye-sensitized solar cells, and the photovoltaic performance of DSSCs based on composite electrodes are investigated. The results show the cell with NaYF₄:Yb³⁺, Er³⁺ achieves a power conversion efficiency of 7.65% under one sun illumination (AM 1.5G, 100 mW cm⁻²), which is an increase of 14% compared to the cell without NaYF₄:Yb³⁺, Er³⁺ (6.71%). The performance improvement is attributed to the dual effects of enhanced light harvesting from extended light absorption range and increased light scattering, and lower electron transfer resistance.
