Efficiency improvement of crystalline-Si solar cell using the combination of Europium doped silicate phosphors down shifting and SiO 2 antireflective coating

Impressive efficiency enhancement of 15.38% of crystalline-silicon solar-cell with Eu-doped silicate-phosphors and SiO 2 -layer using spin-on technique is demonstrated. Reflectance, external quantum efficiency, and photovoltaic I-V characteristics are used to examine the downshifting effectiveness.
