چکیده انگلیسی
Yb3+/Er3+ co-doped Y2O3, YOF and YF3 upconversion (UC) phosphors were synthesized by co-precipitation method. The three upconversion phosphor samples show strong green (540â¯nm) and red (660â¯nm) emission bands visible to naked eyes even at the low intense incident light. The potential application of Y2O3, YOF, and YF3 UC phosphors was demonstrated by incorporating them in amorphous silicon thin film solar cells and they showed upconversion current densities of 0.36â¯mA/cm2, 0.23â¯mA/cm2, and 0.207â¯mA/cm2 respectively when the cell was illuminated with a 980â¯nm IR laser. Intensity-dependent J-V studies were carried out to understand the effectiveness of UC phosphors in improving solar cell parameters. An improvement of 7.5% in Jsc was obtained for amorphous silicon solar cell incorporated with YF3 UC phosphors under AM1.5 along with 980â¯nm NIR illumination.
