研究了含有Y2O3: Ho3+/Yb3+上转换（UC）纳米荧光粉的染料敏化太阳能电池（DSSCs）的光散射行为。为了研究UC纳米荧光粉对DSSCs光伏性能的影响，我们将UC纳米荧光粉引入到TiO2薄膜中形成杂化膜。测定了DSSCs的电子喷射能力、电流密度（J(SC)）、开路电压（V-OC）和功率转换效率（PCE）。由于UC纳米荧光粉的近红外到可见光捕获性能得到了改善，因此与DSSCs - TiO2膜相比，DSSCs杂化膜中的J（SC）和PCE分别提高了31%和30%。
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 (J(SC) open-circuit voltage (V-OC), and power conversion efficiency (PCE) of DSSCs have been determined. The enhancement of about 31% and 30% for J(SC) and PCE in DSSCs hybrid film compared with that of DSSCs TiO2 film has been observed due to improved near infrared to visible light harvesting properties of UC nanophosphors.
