Solar Cell : LAM Material : Down Conversion Phosphor

Solar Cell : LAM material : Down Conversion Phosphor

Introduction : The NIR and visible emitting LAM phosphor has been prepared by simple time consuming one step Combustion synthesis process using mixture of two fuels. As synthesized phosphor has been characterised by powder x-ray diffraction (XRD) and photo-luminescence (PL) techniques. The SEM morphology of prepared phosphor have been studied. 
Result : Successfully prepared LAM- Bi²⁺, Eu³⁺ ,Yb³⁺doped phosphors. Strong NIR emission at 980 nm can be ascribed to Yb³⁺ and visible emission of Bi²⁺ and Eu³⁺  around 440 nm to 620 nm in the LAM lattices respectively. Also the visible emission results indicated that blue and red phosphors are suitable candidates for the fabrication of near UV InGaN based LEDs. 

Conclusion : The LAM phosphors are prime candidates for quantum cutting down-conversion phosphor in Si-solar cell and can be used to improve the efficiency of solar cell.
