Abstract
  • Photoluminescence (PL) materials have attracted a lot of attention in last several decades. Recently PL materials, which can convert low-efficiency Ultraviolet (UV) or Infrared (IR) light to high-efficiency visible light, have been widely applied in the research of improving conversion efficiency of solar cell. As one of the most common PL materials, YVO₄:Eu³⁺ Down-shifting (DS) Nanoparticles (NPs) are well researched for improving conversion efficiency of solar cell by prior researchers. However, the transmittance lose due to high reflectance of YVO₄:Eu³⁺ NPs is always the biggest challenge. In this thesis, antireflective materials, hollow silica NPs, are coated with YVO₄:Eu³⁺ NPs for the first time to decrease the reflectance of the YVO₄:Eu³⁺ NPs. Two different morphologies of YVO₄:Eu³⁺ NPs and four DS and/or AR coating modules are compared respectively in this research. In addition, the DS and AR NPs co-coating can improve the solar cell efficiency of Si-based solar cell by 6.54 than the efficiency of Si-based solar cell without DS and AR NPs co-coating.
