This paper presents sputtered-deposited Ag nanoparticles (NPs) on the encapsulant material\n(ethylene vinyl acetate, EVA) with the variation of annealing condition on crystalline silicon solar\ncell to enhance the light intensity, and a conventional solar cell is also performed for comparison.\nIt was found that an increase in the transmittance at the wavelength of 500 - 800 nm was detected\nin the Ag nanoparticle solar cells. And red-light enhancement of around 2% was measured in the\nAg-sputtered solar module under annealing condition of 700C for 3 min from incident photon to\nconverted electron (IPCE) profile. The photovoltaic performance of solar modules was characterized\nby a flasher system in AAA class (temporal instability, spectral match, and irradiance nonuniformity).\nThe IV curve showed a current enhancement with Ag-EVA sample, and thus a high\npower output around 0.250 W was observed. A high fill factor of 73.63% also implied a high performance\nin series and shunt resistance. Surface plasmonic resonance effects of Ag nanoparticles\ndeposited on the surface of solar cell were examined and discussed. This paper not only illustrated\nthe performance of the surface plasmonic resonance of a solar device but also verified the application\nin the industrial production.
