Abstract
The combination of plasmonic scattering of silver nanoparticles (Ag-NPs) embedded in SiO 2 layer and luminescent downshifting (LDS) of Eu-doped phosphor layer applied on silicon solar cells to enhance photovoltaic performances was demonstrated. By annealing 3, 5, and 7 nm thick silver films at 200 �XC for 30 min under ambient H 2 to form Ag NPs of various dimensions were obtained, which corresponding to the average dimensions of Ag-NPs are 20.13, 25.03, and 32.14 nm determining by SEM images. The optical and electrical properties of the cells with Ag-NPs embedded in a SiO 2 antireflection coating (ARC) were characterized firstly by optical reflectance, absorbance, and external quantum efficiency (EQE) measurements. Larger AgNPs dimension of 32.14 nm exhibited a larger short-circuit current-density (J sc ) enhancement of 31.24 %, which is higher than that of 30.90% for Ag-NPs dimension of 25.03 nm and 28.64% for Ag-NPs dimension of 20.13 nm. The combined effects of plasmonic scattering and LDS are studied by applying Ag-NPs and Eu-doped phosphor particles within SiO 2 ARC, which the J sc enhancement can be further enhanced from 28.64% to 29.37%.
