Comprehensive optimization of a nanoparticle fabrication process for enhanced performance of polycrystalline silicon thin-film solar cells is presented. Three factors were studied: the Ag precursor film thickness, annealing temperature and time. The thickness of the precursor film was 10, 14 and 20nm; annealing temperature was 190, 200, 230 and 260°C; and annealing time was varied between 20 and 95min. Performance enhancement due to light-scattering by nanoparticles was calculated by comparing absorption, short-circuit current density and energy conversion efficiency in solar cells with and without nanoparticles formed under different process conditions. Nanoparticles formed from 14-nm-thick Ag precursor film annealed at 230°C for 53min result in the highest absorption enhancement in the 700-1,100nm wavelength range, in the highest enhancement of total short-circuit current density. The highest photocurrent enhancement was 33.5%, which was achieved by the cell with the highest absorption enhancement in the 700-1,100nm range. The plasmonic cell efficiency of 5.32% was achieved without a back reflector and 5.95% with the back reflector; which is the highest reported efficiency for plasmonic thin-film solar cells.
